Cardiometabolic Profile in Young Adults With Diverse Cigarette Smoking Histories: A Longitudinal Study From Adolescence.

BACKGROUND: For the first time, the present study investigated smoking trajectory and cardiometabolic profile from adolescence to young adulthood in a middle-income developing country facing a high prevalence of smoking and cardiovascular disease-related outcomes. METHODS AND RESULTS: Data on 1082 adolescents (12-18 years of age) who participated in the TLGS (Tehran Lipid and Glucose Study) were gathered, and participants were followed for a median of 12.5 years (baseline: 1999-2002, last follow-up: 2014-2017). Participants were categorized as non/rare smokers, experimenters, and escalators using group-based trajectory models. Statistical analysis was used to compare the trajectory groups' cardiometabolic components, clinical characteristics, and cardiometabolic changes due to the individuals' placement in experimenter and escalator groups compared with non/rare smokers. The smoking trajectory groups in young adulthood differ significantly in blood pressure, triglycerides, high-density lipoprotein cholesterol, waist circumference, and body mass index, with the escalator group having the highest risk values for each component. Significant differences were observed in blood pressure (P=0.014), triglycerides (P<0.001), and waist circumference (P<0.001) status after using clinical cut points. The adjusted linear regression revealed that the escalator group had 3.16 mm Hg-lower systolic blood pressure SBP (P=0.016), 2.69 mm Hg-lower diastolic blood pressure (P=0.011), and 4.42 mg/dL-lower high-density lipoprotein cholesterol (P=0.002), compared with the non/rare smoker group. CONCLUSIONS: Despite elevated risks in unadjusted analyses for all cardiometabolic components among smokers, our study identified a modest protective link between early smoking and blood pressure in addition to a remarkable harmful association with high-density lipoprotein cholesterol levels exclusively in the escalator group during the developmental stage to young adulthood, using adjusted analyses.

Socio-behavioral determinants of health-related quality of life among patients with type 2 diabetes: comparison between 2015 and 2018.

INTRODUCTION: Type 2 diabetes (T2D) is a common chronic disease that significantly affects an individual's overall health and well-being. The aim of this study is to investigate the factors that influence the health-related quality of life (HRQoL) of patients with T2D. METHODS: This study conducted using data from 6th phase (2015-2017) and 7th phase (2018-2022) of the Tehran Lipid and Glucose Study (TLGS). Data were collected through a combination of interviews, physical examinations, and laboratory tests. Quality of life questionnaire (SF-12) that consists of 12 questions was used to assess physical and mental health functioning. The generalized estimating equation model was used to assess the association between socio-behavioral factors and changes in HRQoL. RESULTS: The study included 498 patients with T2D. The changes in HRQoL in patients with T2D followed a sex-specific pattern. Analysis of the physical component score (PCS) and the mental component score (MCS) showed a non-significant change in the total score during the three-year longitudinal study. However, the role physical (RP) of the PCS and the social functioning (SF) of the MCS showed a statistically significant change during this period. In addition, sex, body mass index (BMI), and having cardiovascular disease (CVD) and chronic kidney disease (CKD) showed a significant association with RP changes, and only job status showed a significant association with SF changes. CONCLUSIONS: By recognizing the sex-specific patterns in HRQoL changes and understanding the multifaceted nature of factors such as BMI, CVD and CKD, healthcare professionals can develop targeted interventions that go beyond traditional diabetes management.

Worse becomes the worst: obesity inequality, its determinants and policy options in Iran.

Background: This tracked obesity inequality and identified its determinants among the population of Iran. In addition, it examined the impact of implemented policies on these inequalities. Methods: This study was performed in two phases. First, we conducted a rapid review of the disparity in obesity prevalence in Iran. Then we investigated the main determinants of this inequality in a qualitative study. In addition, we examined Iran's policies to deal with obesity from the perspective of equality. We conducted 30 Semi-structured interviews with various obesity stakeholders selected through a purposive snowball sampling method between November 25, 2019, and August 5, 2020. In the inductive approach, we used the content analysis method based on the Corbin and Status framework to analyze the data using MAXQDA-2020. The consolidating criteria for reporting a Qualitative Study (COREQ-32) were applied to conduct and report the study. Results: Inequalities in the prevalence of obesity in terms of place of residence, gender, education, and other socioeconomic characteristics were identified in Iran. Participants believed that obesity and inequality are linked through immediate and intermediate causes. Inequality in access to healthy foods, physical activity facilities, and health care are the immediate causes of this inequality. Intermediate factors include inequality against women, children, and refugees, and inequality in access to information, education, and financial resources. Policymakers should implement equity-oriented obesity control policies such as taxing unhealthy foods, subsidizing healthy foods, providing healthy and free meals in schools, especially in disadvantaged areas, and providing nutrient-rich foods to low-income families. Also, environmental re-engineering to increase opportunities for physical activity should be considered. Of course, for the fundamental reduction of these inequalities, the comprehensive approach of all statesmen is necessary. Conclusion: Obesity inequality is a health-threatening issue in Iran that can prevent achieving human development goals. Targeting the underlying causes of obesity, including inequalities, must be considered.

Outcomes of a homestead food production program on nutritional knowledge, dietary diversity, food security and empowerment of rural women in Tehran province, Iran.

BACKGROUND: Food and nutrition insecurity is a major health issue in developing countries. Homestead food production (HFP) programs are strategies for improving food and nutrition security of a country. Iran implemented a HFP program entitled "Nutrition Improvement of Rural and Nomadic Women" in its villages for a five-year period from 2017. The current study assessed the outcomes of this mentioned program and its determinants among rural women in Tehran province. METHODS: The population of this cross-sectional study comprised a group covered by the program (n = 143) and a non-covered group (n = 160). The participants were selected randomly from 32 villages of five counties in Tehran province. Data was collected using five questionnaires: (1) General information, (2) Women's empowerment, (3) Nutritional knowledge, (4) Dietary diversity, and (5) Household Food Insecurity Access Scale (HFIAS). Data was analyzed using the IBM SPSS version 21 and the IBM Amos SPSS version 22 software. RESULTS: The results of the study showed no significant improvement in the expected indicators, such as frequency of home gardening, nutritional knowledge, dietary diversity, women's empowerment, and household food insecurity status among women covered by the program (p > 0.05). The structural equation modelling (SEM) results indicated that women's empowerment from the dimension of decision-making power (r = 0.151) and nutritional knowledge (r = 0.135) were the significant positive predictors of dietary diversity (p < 0.05), while household food insecurity predicted it negatively (r=-0.138) (p < 0.05). CONCLUSION: Because the current evaluated program has not been able to improve the expected indicators, modification of the program implementation may be needed, such as: addressing the probable barriers and challenges and strengthening the facilities in the covered villages. The current study presents a model of the dietary diversity predictors for consideration in redesigning or enhancing the program.

The association between leisure-time physical activity and blood pressure changes from adolescence to young adulthood: Tehran Lipid and Glucose Study.

The effectiveness of long-term leisure time physical activity (LTPA) on blood pressure (BP) changes is still under debate. Since adolescence lifestyle behaviors shape the adulthood health profile, this study aimed to investigate the sex-specific impact of LTPA on BP changes from adolescence to young adulthood. This longitudinal study uses the data of 1412 adolescents (52% females) aged 12-18 years through a median follow-up of 12.2 years in the Tehran Lipid and Glucose Study (TLGS) framework. LTPA was calculated using the reliable and valid Iranian version of the modified activity scale (MAQ), and BP was measured at least twice by trained physicians. The linear mixed model was used to examine the study variables, considering individual and intrapersonal differences during the study. The majority of participants consistently demonstrated insufficient LTPA throughout the follow-up assessments, ranging from 54.7 to 67.1% for males and 77.7-83.4% for females. Despite a declining trend in LTPA (ß = - 2.77 for males and ß = - 1.43 for females), an increasing trend was noticeable in SBP, DBP, and BMI (ß = 1.38, ß = 1.81, ß = 0.97 for males, and ß = 0.10, ß = 0.20, ß = 0.97 for females, respectively). The unadjusted model revealed a significant trend in all variables for both sexes, except for female BP (P = 0.45 for SBP and P = 0.83 for DBP). Using the adjusted model, no significant association was observed between LTPA and changes in BP over time in both sexes. Our study indicates no association between LTPA and BP changes from adolescence to young adulthood. Insufficient LTPA levels, particularly among Iranian females, are likely the primary factor. Further research is crucial to identify appropriate LTPA levels to promote cardiovascular health and implement targeted interventions to achieve optimal LTPA levels in the Iranian population.

In silico and In vitro Assessment of Antibacterial Activity, LPS Binding Affinity, and Toxicity of the GKY25 Peptide.

INTRODUCTION: Extensively and multi-drug resistant isolates of bacteria (MDR, XDR) have caused significant health problems and are responsible for high morbidity and mortality as well. In this critical condition, the discovery, design, or development of new antibiotics is of great concern. According to this necessity, antimicrobial peptides (AMPs) suggested as promising agents. Accordingly, this study aims to evaluate the GKY25 peptide to develop its future antibacterial applications as well as confirmation of LPS neutralization. METHODS: Predictions of 3D structure and helical wheel projection analysis of the peptide were performed by ITASSER and Heliquest servers. Binding affinity and antibacterial activity were performed using molecular docking and CAMPR4, respectively, followed by experimental binding assay as well as in vitro antibacterial assay. RESULTS: GKY25 was predicted as an alpha-helical peptide, and its helicity showed probable projection of hydrophobic and positively-charged amino acid residues. Docking studies showed binding affinity of GKY25 peptide to gram-positive and outer and inner gram-negative bacterial membranes as -5.7, -6.8, and -4 kcal/mole, respectively. CAMPR4 analysis predicted the peptide as an AMP. Experimental binding assay showed that the peptide binds LPS immediately and their interaction was observed at 274 nm. CONCLUSION: Gathering all in silico and in vitro data together, GKY25 is a good drug lead that could be examined further using clinical isolates of gram-negative bacteria in vitro.

How Do Active and Passive Cigarette Smokers in Iran Evaluate Their Health? A Sex-Specific Analysis on the Full-Spectrum of Quality of Life.

INTRODUCTION: This study aimed to determine the sex-specific effects of active and passive cigarette smoking on the full spectrum of health-related quality of life (HRQoL) among a sizeable adult population. METHODS: This study was conducted within the Tehran Lipid and Glucose Study (TLGS) framework. Participants included 7478 adults in the last examination of the TLGS. We used a quantile regression model to compare sex-specific HRQoL distributions among non-, current, and passive smokers. Two-step cluster analysis was used to consider the synergic effects of confounder variables. RESULTS: In men, current smoking was negatively associated with only mental HRQoL in all percentiles of its distribution with a decrease in absolute estimation values from the lowest (5 th: ß=-6.59, p<0.001) to the highest (90 th: ß=-0.93, p=0.027). Also, passive smoking was negatively associated with men's physical HRQoL in the upper percentiles of its distribution (75 th: ß=-1.12, p=0.010; 90 th: ß=-1.26, p=0.016). In women, the current (ß= -4.17 to -4.45 for 25 th to 90 th percentiles) and passive smokers (ß= -2.05 to -4.25 for 10 th to 90 th percentiles) had lower mental HRQoL in the mentioned percentiles. Also, the current smoking had a negative association with the 5 th percentile (ß=-2.04, p=0.008), and a positive association with the 50 th (ß=1.94, p< 0.008) and 75 th percentile of physical HRQoL (ß=2.25, p=0.004). CONCLUSIONS: The present study showed the harmful effect of smoking on mental HRQol in all participants. In contrast, the physical effect of smoking was only observed in female active smokers and at the extreme levels of the physical HRQoL spectrum. IMPLICATIONS: According to the harmful effect of smoking on HRQoL, understanding active and passive smokers' perceptions of how smoking impacts their health is critical for tobacco control programs. Since most previous studies of smoking and HRQoL have mainly focused on the extreme parts or central values of the HRQoL distribution, the use of a multiple regression approach enables the evaluation of other parts of the conditional distribution of the outcome variable. This study demonstrated the prominent effect of smoking on the mental HRQoL as well as the more serious public health burden of passive smoking in women.

Men's Smoking Trajectories and Health-Related Quality of Life in the Whole Family: Tehran Lipid and Glucose Study.

Background: We aimed to investigate the latent smoking classes in men and their association with health-related quality of life (HRQoL) of themselves, their wives and offspring. Methods: Using Tehran Lipid and Glucose Study (TLGS), 1781 men with marital stability and 8-18-year-old offspring were followed for 15 years (1999-2014). Latent class growth modeling (LCGM) was used to identify men's smoking patterns in 1139 men with at least three non-missing measurements of cigarettes per day (CPD); they had 1908 children (8-18 years at baseline). HRQoL and its physical and mental component summaries (PCS and MCS) was measured at the last follow-up using the SF-12v2 questionnaire. The associations of men's smoking classes with HRQoL of the family members were examined using generalized linear model. Results: LCGM revealed four trajectories for men's smoking patterns; non/rare smokers, decreasing light, persistent moderate smokers, and persistent heavy smokers. Persistent smoking men, regardless of the amount of smoking (light or heavy), had lower scores in general health (ß= -7.80 for moderate and ß= -10.71 for heavy class) but not overall PCS. Al three trajectories of smoker men had poorer overall MCS than non/rare smokers. Living with persistent heavy smoker men was associated with decreased overall MCS in women (ß= -4.20), in particular role emotional (ß= -8.82) and mental health (ß= -9.42). No significant association was detected between fathers' smoking patterns and offspring HRQoL in young adulthood. Conclusion: Our results show men's heavy and persistent smoking worsens their own and their spouses' HRQoL, mainly in mental health dimensions.

Health-related quality of life in women with various levels of spiritual health.

This study investigates for the first time the relationship between spiritual health (SH) and health-related quality of life (HRQoL) in different periods of life in healthy women, which could be important in the current critical post-pandemic situation. We recruited data from 2238 healthy women in the Tehran Lipid and Glucose Study (TLGS) framework, performed a cross-sectional study, and divided them into four age groups: 1) 20-34, 2) 35-44, 3) 45-54, and 4) 55≤ years. HRQoL and SH were measured using Short-Form 12-Item Health Survey version 2 and spiritual health inventory in Muslim adults (SHIMA-48). We defined low and high SH as the first and third tertile of SHIMA-48 scores. Most participants were in the first age group (39 percent), were married (74.7 percent), and were housewives (74.7 percent). The mean mental component summary score and its domains were directly associated with age. This subscale was significantly higher in individuals with high SH scores in all age groups. However, except for general health, other physical subscales did not differ significantly between the two levels of SH among the age groups studied. Results indicate higher HRQoL, especially mental health, in healthy women with increased spiritual well-being. This finding can be used in programs to improve psychological health in women.

Cohort profile update: Tehran cardiometabolic genetic study.

The Tehran cardiometabolic genetic study (TCGS) is a large population-based cohort study that conducts periodic follow-ups. TCGS has created a comprehensive database comprising 20,367 participants born between 1911 and 2015 selected from four main ongoing studies in a family-based longitudinal framework. The study's primary goal is to identify the potential targets for prevention and intervention for non-communicable diseases that may develop in mid-life and late life. TCGS cohort focuses on cardiovascular, endocrine, metabolic abnormalities, cancers, and some inherited diseases. Since 2017, the TCGS cohort has augmented by encoding all health-related complications, including hospitalization outcomes and self-reports according to ICD11 coding, and verifying consanguineous marriage using genetic markers. This research provides an update on the rationale and design of the study, summarizes its findings, and outlines the objectives for precision medicine.

Adapting the Community Readiness Model and Validating a Community Readiness Tool for Childhood Obesity Prevention Programs in Iran.

OBJECTIVES: It is critical to assess community readiness (CR) when implementing childhood obesity prevention programs to ensure their eventual success and sustainability. Multiple tools have been developed based on various conceptions of readiness. One of the most widely used and flexible tools is based on the community readiness model (CRM). This study aimed to adapt the CRM and assess the validity of a community readiness tool (CRT) for childhood obesity prevention programs in Iran. METHODS: A Delphi study that included 26 individuals with expertise in 8 different subject areas was conducted to adapt the CRM into a theoretical framework for developing a CRT. After linguistic validation was conducted for a 35-question CR interview guide, the modified interview guide was evaluated for its content and face validity. The quantitative and qualitative analyses were performed using Stata version 13 and MAXQDA 2010, respectively. RESULTS: The Delphi panelists confirmed the necessity/appropriateness and adequacy of all 6 CRM dimensions. The Persian version of the interview guide was then modified based on the qualitative results of the Delphi study, and 2 more questions were added to the community climate dimension of the original CRT. All questions in the modified version had acceptable content and face validity. The final CR interview guide included 37 questions across 6 CRM dimensions. CONCLUSIONS: By adapting the CRM and confirming linguistic, content, and face validity, the present study devised a CRT for childhood obesity prevention programs that can be used in relevant studies in Iran.

Improving community readiness among Iranian local communities to prevent childhood obesity.

BACKGROUND: Community Readiness Intervention for Tackling Childhood Obesity (CRITCO) is a theory-based intervention being developed to improve the readiness of an Iranian urban population to engage in childhood obesity prevention programs. This study aimed to explore changes in readiness of intervention and control local communities from diverse socio-economic areas of Tehran. METHODS: This study was a seven-month quasi-experimental intervention implemented in four intervention communities and compared with four controls. Aligned strategies and action plans were developed around the six dimensions of community readiness. The Food and Nutrition Committee was established in each intervention community to make collaborative efforts among different sectors and assess the fidelity of the intervention. The pre-and post- readiness change was explored through interviews with 46 community key informants. RESULTS: The total readiness of intervention sites increased by 0.48 units (p < 0.001) and shifted to the next higher level, from preplanning to the preparation stage. At the same time, the readiness of control communities decreased by 0.39 units (p < 0.001), although their readiness stage remained unchanged, reflecting the fourth stage. Also, a sex-dependent CR change was observed, such that the girls' schools showed a more remarkable improvement in interventions and less decline in controls. The readiness stages of interventions significantly improved for four dimensions related to community efforts, knowledge of the efforts, knowledge of childhood obesity issue, and leadership. Furthermore, the readiness of control communities significantly decreased on three of six dimensions related to community effort, knowledge of efforts, and resources. CONCLUSIONS: The CRITCO successfully improved the readiness of intervention sites for addressing childhood obesity. It is hoped that the present study can be a spark for developing readiness-based childhood obesity prevention programs in Middle Eastern and other developing countries. TRIAL REGISTRATION: The CRITCO intervention was registered at Iran Registry for Clinical Trials ( http://irct.ir ; IRCT20191006044997N1) on 11/11/2019.

Health-Related Quality of Life in Those with Persistent or Transient Obesity Phenotypes during Two Decades: Tehran Lipid and Glucose Study.

INTRODUCTION: The current study aimed to investigate the association of three stable obesity phenotypes (persistent metabolically healthy normal weight [P MHNW], persistent metabolically healthy obese [P MHO], persistent metabolically unhealthy obese [P MUO]), and one transient (MHO to MUO) obesity phenotype throughout 18 years with health-related quality of life (HRQoL). METHODS: 1,932 participants (649 men and 1,283 women) who completed the HRQoL questionnaire during 2016-2019 were recruited in the current investigation. Based on the body mass index and metabolic status, participants were classified into four obesity phenotypes, including (1) P MHNW, (2) P MHO, (3) P MUO, and (4) transient from MHO to MUO. The HRQoL was compared between groups using analysis of covariance. Participants' age, marital status, occupation status, education level, physical activity, and smoking were adjusted. RESULTS: After adjustment for confounder variables, a significant difference among obesity phenotypes was indicated in (physical component summary) PCS scores of both sexes and (mental component summary) MCS scores just in women (p value = <0.001). The P MUO had the lowest scores in PCS and MCS, and P MHO had the highest MCS scores compared to other obesity phenotypes in either sex. CONCLUSION: The results of the present study indicate the negative effect of long-term concurrence of obesity and metabolic disorders on the HRQoL of adults. However, long-term obesity alone or loss of metabolic health in the short term did not affect individuals' assessment of their physical and mental health. These findings highlight the importance of preventive interventions in people with obesity; also indicate the need for awareness-raising strategies about healthy lifestyles to improve the quality of life in society.

A 10-Year Cardiovascular Risk in Adults with Different Levels of Spiritual Health: Tehran Lipid and Glucose Study.

Background: Previous studies have shown that spiritual experience may reduce cardiovascular disease (CVDs). However, little is known about the relationship between spiritual health and the gender-specific risk of CVDs in communities with different cultures. Methods: A total of 3249 individuals (53.7% female, 75.0% middle-aged) participated in the Tehran Lipid and Glucose Study (TLGS) from 2015 to 2017 were included. Based on the ACC/AHA pooled cohort equation, CVD risk over ten years was examined. Spiritual health was measured using a developed tool for measuring spiritual health in Muslim populations (SHIMA-48). Linear regression models were used to assess the association between spiritual health and ACC/AHA risk scores. The natural logarithm scale was calculated to consider the normal distribution hypothesis of the regression model. Results: The current results suggest a slight but significant increase in the mean of spiritual health in women compared to men in both cognitive/emotional and behavioral dimensions (P < 0.001). In both sexes, a higher prevalence of smoking was observed in participants with lower levels of spiritual health (P < 0.004). In men, compared to those with a low level of spiritual health (the first tertile), the logarithm of the ACC-AHA risk score was reduced by 0.11 (P = 0.004) and 0.18 (P < 0.001) for those in the second and third tertiles of spiritual health, respectively. This result may be attributed to higher cigarette smoking among the latter group. Similar results were not observed in women. Conclusions: Current results indicate a gender-specific association between spiritual health and cardiovascular disease risk. Our findings imply that promoting spiritual health can be considered an effective strategy in future preventive interventions, primarily by controlling the desire to smoke in men.

Active and Passive Smoking in Adults Undergoing a Long-Term Multi-Setting Healthy Lifestyle Education: Tehran Lipid and Glucose Study.

We aimed to investigate the effects of a multi-setting lifestyle education on men's cigarette, hookah, and passive smoking, and women's passive smoking, in Iran. Data of Tehran Lipid and Glucose Study (TLGS) were used. TLGS started in 1999 with every-3-year follow-ups. Multi-stage cluster random sampling was used to recruit participants under the coverage of three health centers. One health center implemented multi-setting lifestyle education at school, family, and community setting. Our analytic sample for generalized estimating equation was restricted to 1322 and 3593 adults (respectively as intervention and control) who were followed for 15.8 years. Intervention reduced the odds of men's cigarette smoking by 27%. The estimated mean cigarettes/day was 1.58 lower in intervention men. The intervention reduced the odds of men's hookah use by 42% in short term. Intervention women had 33% lower odds of passive smoking. Lifestyle education with community outreach can help achieve pragmatic tobacco control goals.

A Qualitative Exploration of Body Image from the Perspective of Adolescents with a Focus on Psychological Aspects: Findings from Iran.

The current study employs a qualitative approach to uncover the perceptions of Iranian adolescents regarding their bodies, with a focus on the psychological components that contribute to their body image perceptions. Data collection conducted using 13 semi-structured focus group discussions with 42 girls and 42 boys (15-18 years). All focus group discussions were audio recorded and transcribed verbatim. Data analysis was done manually using constant comparative analysis according to the Strauss and Corbin analysis method. Based on the participants' statements, four main themes and related categories emerged from data: (1) Beliefs including uncontrollable body, biased opinion of those around, priority of health, spiritual/religious beliefs and affecting future success, (2) Body-evaluation including direct body evaluation and indirect body evaluation, (3) Feelings and emotions including disgust and hatred, frustration, sadness, shame, envy, fear, approval and satisfaction and (4) Behaviors including lifestyle modifications, beautifying and using make up, extreme dieting, physical inactivity, avoidance behaviors, passive behaviors, aggressive behaviors and social isolation. Findings of the current study provide further information regarding cognitive, emotional and behavioral aspects of body image from the perspectives of adolescents in a West-Asian region.

Barriers Toward the National Program for Prevention and Control of Diabetes in Iran: A Qualitative Exploration.

BACKGROUND: Despite the achievements of the national program for the prevention and control of diabetes (NPPCD) over the past two decades, the available evidence indicates a high prevalence of this disease in Iran. This qualitative study aims to investigate barriers to the NPPCD by pursuing the perspectives of relevant policy-makers, planners, and healthcare workers. METHODS: A grounded theory approach was used to analyze participants' perceptions and experiences. Semi-structured interviews (n=23) and eight focus groups (n=109) were conducted with relevant policy-makers, planners, and healthcare workers in charge of Iran's national diabetes management program. Of the 132 participants, ages ranged from 25 to 56 years, and 53% were female. Constant comparative analysis of the data was conducted manually, and open, axial, and selective coding was applied to the data. RESULTS: Two main themes emerged from data analysis: implementation barriers and inefficient policy-making/ planning. Insufficient financial resources, staff shortage and insufficient motivation, inadequate knowledge of some healthcare workers, and defects in the referral system were recognized as the NPPCD implementation barriers. Inappropriate program prioritizing, the lack of or poor intersectoral collaboration, and the lack of an effective evaluation system were the inefficient policy-making/planning problems. CONCLUSION: Current results highlighted that inefficient policy-making and planning have led to several implementation problems. Moreover, the key strategies to promote this program are prioritizing the NPPCD, practical intersectoral collaboration, and utilizing a more efficient evaluation system to assess the program and staff performance.

Body mass index trajectories from childhood concerning emotional states in young adulthood: Tehran Lipid and Glucose Study.

This study aimed to identify body mass index (BMI) trajectories from childhood and their relationships with depression, anxiety, and stress symptoms in young adulthood. A total of 687 children aged 4-18 years were recruited from the Tehran Lipid and Glucose Study. Throughout 18 years of follow-up, BMI was measured every 3 years for a maximum of 6 data points. Participants completed the depression, anxiety, and stress scale in their young adulthood (aged 22-36). The group-based trajectory modelling was applied to identify BMI patterns. The logistic regression model was used to assess the association between BMI trajectories and depression, anxiety, and stress symptoms in adulthood. Two BMI trajectories were identified from childhood to young adulthood: healthy weight (HW = 69.6%) and persistent increasing overweight/obesity (PIO = 30.4%). After adjusting for potential confounders, compared with the HW group, men in the PIO group were more likely to experience higher stress levels (OR: 1.62, 95% CI: 0.99-2.63; p = 0.05). No significant association was observed between the PIO trajectory and depression and anxiety among both sexes and stress symptoms in females. Our results highlight that developing overweight and obesity from childhood may be related to increased stress in males.

Cigarette smoking trajectories among adolescents and young adults in the Islamic Republic of Iran.

Background: Cigarette smoking follows a progressive pattern throughout the lifetime; most adult smokers started smoking during adolescence. Aim: To understand the cigarette smoking trajectories and their predictors among adolescents and young adults in the Islamic Republic of Iran. Methods: Using data from the Tehran Lipid and Glucose Study, we followed 1169 adolescents (12-18 years old) into their young adulthood (28-32 years old), from 2002 to 2016. We used cigarette smoking as the outcome variable for group-based trajectory modelling. After detecting the trajectories, we investigated the effects of independent variables, namely, individual employment; education; physical activity; and paternal smoking, employment and education, on the trajectories. We analysed the data using STATA version 16 and SPSS version 26. Results: Three trajectories were detected: non-smokers (79%), experimenters (12%) and escalators (9%). Boys were approximately 3 times (OR = 2.94, 95% CI: 2.32-3.24, P < 0.001) and 25 times (OR = 25.00, 95% CI: 23.92-26.08, P < 0.001), respectively, more likely than girls to be in the experimenter and escalator groups. Receiving a university education decreased the odds of being in the escalator trajectory for 18% (OR = 0.82, 95% CI: -0.04-0.96, P = 0.002) of the study participants. Employment after high school increased the odds by approximately two folds for the experimenter (OR = 2.00, 95% CI: 1.42-2.50, P = 0.01) and escalator (OR = 2.33, 95% CI: 1.33-2.93, P = 0.03) trajectories. Paternal smoking was associated with 1.88 and 2.23, respectively, increased odds of experimenting and escalating smoking among the adolescents. Conclusion: Iranian adolescents follow 3 cigarette smoking trajectories into young adulthood: non-smokers, experimenters and escalators. Male sex, employment after high school, and living with a smoker father were associated with unfavourable smoking patterns. Findings from this study provide valuable insights for designing targeted interventions to reduce cigarette smoking among adults and adolescents in the Islamic Republic of Iran.

Self-rated Health in Youth with Different Screen Time in Their Adolescence: Tehran Lipid and Glucose Study.

BACKGROUND: The long-term effects of childhood screen time on health-related quality of life (HRQoL) are still unclear. This study aimed to investigate the relationship between screen time during adolescence and sex-specific HRQoL in early youth. METHODS: We studied the data from 642 adolescents aged 13-19 years, who participated in the Tehran Lipid and Glucose Study from 2005 to 2011 (baseline) with complete data on HRQoL in their early adulthood (22-28 years at the last follow-up). Physical and Mental HRQoL were assessed using the Iranian version of the short-form 12-item health survey version 2 (SF-12v2). Screen time and leisure-time physical activity were evaluated using the Iranian Modifiable Activity Questionnaire (MAQ). All analyses were conducted in Stata (version 14); MI used the mi impute command. RESULTS: The mean±SD of age, body mass index (BMI), and physical activity in childhood were 16.33±1.27, 23.27±4.63 and 13.77±16.07, respectively. Overall, 35% of boys and 34% of girls had high screen time (HST) in childhood. In general, the HRQoL scores in male participants were higher than in females in both the mental and physical domains. HST in males in childhood was associated with decreased mental health (ß=-6.41, 95% CI: -11.52, -1.3 and P=0.014), social functioning (ß=-5.9, 95% CI: -11.23, -0.57 and P=0.03) and mental component summary (MCS) (ß=-2.86, 95% CI: -5.26, -0.45 and P=0.02). The odds of poor MCS were significantly higher in those with HST compared to their counterparts with low screen time (LST) after adjusting for all potential cofounders. CONCLUSION: The results of the present study showed the negative effect of screen time during adolescence on HRQoL in early youth. This effect was observed in men, mainly in the mental dimension. Investigating the long-term consequences of screen-time behaviors on self-assessed health in other populations with the aim of effective primary prevention is also suggested.
