RESUMO

BACKGROUND: Rates of depression among Pakistani mothers are high, leading to poor developmental outcomes in their children. This study tested the effectiveness of a manualized integrated parenting program; Learning through Play Plus (LTP+) for maternal depression in Karachi, Pakistan. METHODS: A cluster randomized control trial conducted from January 2014 to December 2015 across 120 villages in Karachi. A total of 774 depressed mothers aged 18-44 years with children aged 0-30 months old, were included. Villages were randomized to receive LTP+ added to treatment as usual (TAU) or TAU alone. Primary outcomes were severity of maternal depression at 3 and 6 months measured by the Edinburgh Postnatal Depression Scale and child socio-emotional development at 6 months measured by the Ages and Stages Questionnaire (ASQ). Secondary outcomes included maternal anxiety, quality of life, social support, parenting competence, and knowledge about child development. RESULTS: Mothers in the LTP+ group reported significantly lower depression scores compared to those in the TAU group (6.6 vs. 13.8, effect size [ES]: -7.2; 95% confidence interval [CI]: -8.2, -6.1) at 3 and 6 months (7.2 vs. 12.00; ES: -4.6; 95% CI: -5.9, -3.4). Child socio-emotional development at 6 months was significantly better in the LTP+ group on all domains of the ASQ. There were also statistically significant improvements on all secondary outcomes at 3- and 6-month follow-up. CONCLUSION: In low-resource settings like Pakistan, low-cost integrated parenting interventions delivered by lay health workers can provide effective treatment for depressed mothers, leading to improvements in child development.

RESUMO

BACKGROUND: The physical and social environments surrounding food, whether perceived or observed, can influence consumers' food choices by changing food access, and affordability, or by changing settings where food-related behaviors occur. AIM: To describe older adults' perceived food environment, identify the most important sites and factors that enable healthy eating, and explore older adults' recommendations for communities to facilitate fruit and vegetable consumption. METHODS: Participants aged 60 and older from metropolitan areas in Massachusetts, Iowa, and Illinois completed a researcher-administered survey to rate the perceived environment including accessibility, availability, and affordability of fruits and vegetables, and perceived importance of factors and establishments related to fruit and vegetable consumption. Participants also suggested changes for establishments to facilitate fruit and vegetable consumption. RESULTS: The majority of the 142 participants perceived their food environment for fruits and vegetables as not difficult to access (85.2%) with good or excellent availability (90.1%). Education, marital status, and race were associated with some aspects of the perceived food environment. Perceived accessibility and supermarkets were rated as the most important factor and establishment, respectively, to facilitate fruit and vegetable consumption across all study sites. Participants proposed recommendations to address the availability, quality, accessibility and affordability of fruits and vegetables. CONCLUSION: Interventions promoting accessible, affordable, quality fruits and vegetables may improve older adult consumers' perceptions of their food environment. Communities may also use undervalued resources such as mobile markets more strategically to provide additional support for healthy eating in older adults.

RESUMO

BACKGROUND: The risk factors and adverse outcomes related to maternal depression and child malnutrition are a leading cause of morbidity and mortality in low and middle-income countries (LMIC) including Pakistan. Above 25% of women suffer from maternal depression. Up to 50% children are under-nourished which contributes to 35% of all under-5 deaths in the country. AIM: To determine the efficacy of Learning through Play Plus Thinking Healthy Program (LTP Plus) intervention to reduce maternal depression in mothers with undernourished children. METHODS: In this randomised controlled trial, all eligible mothers presenting to the paediatric departments were invited to participate in the study. Out of the total 256 mothers screened, 107 were included, 54 of those were randomly allocated to LTP Plus group and 53 to treatment as usual (TAU). Edinburgh Postnatal Depression Scale (EPDS) was used to screen for depression. Hamilton Depression Rating Scale (HDRS), Maternal Attachment Inventory (MAI), Social Support Scale (OSLO-3) and the Euro-QoL (EQ-5D) were used to measure the severity of depression, mother-child attachment, level of support and health related quality of life dimensions. Assessments were completed at baseline, end of intervention (3 months from baseline) and at 6 months from baseline. RESULTS: Mothers in the LTP Plus group significantly showed improvements in depression (p<0.001), social support (p = 0.02) and quality of life (p<0.001) at the end of the intervention (LTP Plus), as compared to the TAU group, which were sustained up to 6 months after baseline. CONCLUSION: The outcomes of LTP Plus intervention for mothers of malnourished children show promising results in reducing maternal depression and improving child outcomes. A full trial with longer-term outcomes and cost-effectiveness needs to be conducted.

RESUMO

Community planners such as policymakers and health care and nutrition service providers can create an "age-friendly" environment to support healthy eating in older residents by addressing the highest priorities that enable older adults to improve their dietary intake through different food-related community settings. To identify and prioritize these factors that facilitate behavioral change (enablers) and behavioral settings important for older adult nutrition based on the social ecological model, nutrition and aging professionals (n = 30) from two rural (West Virginia, Iowa) and two urban (Massachusetts, New York) city/county regions (communities) participated in an online or live focus group discussion and completed an analytic hierarchy process survey online. Overall, the most important perceived enablers were accessibility and cost, followed by transportation and social support, but their relative importance varied by community. Participants from all communities considered congregate meal sites and food banks among the most important behavioral settings. Participants from most communities considered food stores to be important and also highlighted other settings unique to the area, such as senior housing, neighborhood, and farmers' markets. By targeting interventions to address the most notable enablers and behavioral settings specific to their community, planning groups can enhance their older residents' ability to achieve optimal nutritional health.

RESUMO

OBJECTIVE: Examine compliance with recommended food safety practices in television cooking shows. METHODS: Using a tool based on the Massachusetts Food Establishment Inspection Report, raters examined 39 episodes from 10 television cooking shows. RESULTS: Chefs demonstrated conformance with good retail practices for proper use and storage of utensils in 78% of episodes; preventing contamination (62%), and fingernail care (82%). However, 50% to 88% of episodes were found to be out of compliance with other personal hygiene practices, proper use of gloves and barriers (85% to 100%), and maintaining proper time and temperature controls (93%). Over 90% failed to conform to recommendations regarding preventing contamination through wiping cloths and washing produce. In only 13% of episodes were food safety practices mentioned. CONCLUSIONS AND IMPLICATIONS: There appears to be little attention to food safety during most cooking shows. Celebrity and competing chefs have the opportunity to model and teach good food safety practices for millions of viewers.

RESUMO

A structured interview protocol was used to investigate the ability of older adults (n = 89, age ≥ 65 years) to accurately determine whether three common food items were whole grain, and to assess the package information used in their decision process. Cereal and crackers, which were both whole grain products, were correctly identified by 63% and 66% of participants, respectively. Bread (a refined product), was correctly identified by only 19% of participants, while 46% of participants misidentified the bread as being whole grain. The ingredient list was the information most frequently cited in deciding if a food was whole grain, but participants varied in their ability to accurately interpret it. Package information considered nonpertinent (e.g., the Nutrition Facts label) in identifying a whole grain product was used almost as often as the ingredient list. Older adults would benefit from whole grain education programs that focus on accurately interpreting package information.

RESUMO

Hypertension is one of the most common chronic diseases affecting more than 25% of adults worldwide. In Pakistan, 33% of the adult population suffers from hypertension. Numerous epidemiological studies have demonstrated the critical role of dietary patterns in the causation, prevention and management of hypertension. There's a dearth of evidence from South Asia in this regard. The present study aimed to identify the association between dietary patterns and hypertension among 4304 low income urban adults who participated in the Control of Blood Pressure and Risk Attenuation (COBRA) study in Karachi, Pakistan. Dietary information was collected by a 33- item food frequency questionnaire and 3 unique dietary patterns namely; fat and sweet, fruit and vegetable, and seafood and yogurt patterns were derived using principal component factor analyses. We used univariate and multivariable logistic regression to examine the association between dietary patterns and hypertension. Men were more likely to have hypertension, while increase in age, and body mass index were also associated with hypertension (p<0.001). After adjusting for age, gender, education, marital status, body mass index, and tobacco use; the seafood and yogurt pattern was less likely (OR=0.78: 95% CI: 0.63, 0.98; p-value 0.03) to be associated with hypertension, whereas no significant associations were seen for other two dietary patterns. These findings suggest that certain dietary patterns may be associated with hypertension among Pakistani low income urban adults.

RESUMO

PURPOSE: The purpose of the current study was to engage a local primary care clinic community that serves the Latino immigrant population to obtain their input regarding the design and implementation of a proposed integrated behavioral intervention that will simultaneously target T2DM and depression self-management in this high risk patient population. METHODS: Nine key informant interviews and 3 focus groups were conducted. Key informant interviews were conducted with the medical director, a primary care provider, a diabetes educator, and a medical assistant from each site, as well as the counselor who serves both sites. Fourteen patients with T2DM who screened positive for depression and 7 of their family members participated in the focus groups. Key informants and focus group participants were asked about patient challenges with diabetes management, the role of depression in T2DM, their impressions of the proposed intervention, and motivators and barriers to participation in the intervention. RESULTS: Commonly reported challenges with diabetes management included the struggle with healthy eating and information exchange upon diagnosis. T2DM and depression were seen as interrelated and described by many as having a cyclical relationship. Key informants and focus group participants uniformly supported the proposed intervention and recommended the involvement of family members. CONCLUSIONS: Results of this study support the need and acceptability of individualized behavioral interventions that target T2DM and depression simultaneously.

RESUMO

Temporal lobe epilepsy (TLE) may negatively affect the ability to recognize emotions. This study aimed to determine the cortical correlates of facial emotion processing (happy, sad, fearful, and neutral) in patients with well-characterized left TLE (LTLE) and to examine the effect of seizure control on emotion processing. We enrolled 34 consecutive patients with LTLE and 30 matched healthy control (HC) subjects. Participants underwent functional MRI (fMRI) with an event-related facial emotion recognition task. The seizures of seventeen patients were controlled (no seizure in at least 3months; LTLE-sz), and 17 continued to experience frequent seizures (LTLE+sz). Mood was assessed with the Beck Depression Inventory (BDI) and the Profile of Mood States (POMS). There were no differences in demographic characteristics and measures of mood between HC subjects and patients with LTLE. In patients with LTLE, fMRI showed decreased blood oxygenation level dependent (BOLD) signal in the hippocampus/parahippocampus and cerebellum in processing of happy faces and increased BOLD signal in occipital regions in response to fearful faces. Comparison of groups with LTLE+sz and LTLE-sz showed worse BDI and POMS scores in LTLE+sz (all p<0.05) except for POMS tension/anxiety (p=0.067). Functional MRI revealed increased BOLD signal in patients with LTLE+sz in the left precuneus and left parahippocampus for "fearful" faces and in the left periarcheocortex for "neutral" faces. There was a correlation between the fMRI and Total Mood Disturbance in the left precuneus in LTLE-sz (p=0.019) and in LTLE+sz (p=0.018). Overall, LTLE appears to have a relatively minor effect on the cortical underpinnings of facial emotion processing, while the effect of seizure state (controlled vs. not controlled) is more pronounced, indicating a significant relationship between seizure control and emotion processing.

RESUMO

Many environmental settings and influences can affect food choices and eating behaviors in the growing population of community-dwelling older adults. Using the Social Ecological model, an expert panel participated in online discussions and an Analytic Hierarchy Process survey to identify the most important and changeable environmental settings and enabling factors that promote healthy eating in older adults. Food stores were rated most important when considering accessibility and affordability. Congregate nutrition sites were important for social support along with supporting access and affordability of healthful foods and living accommodations. Senior housing, health care, and religious settings also contributed to the goal of promoting healthful eating in aging adults. Restaurants were rated of lower importance. Based on these results, it is recommended that community food policies include the nutritional needs of older adults by addressing food accessibility and affordability, social support, and living accommodations, with a focus on congregate nutrition sites, food stores, senior housing, health care, and religious organizations.

RESUMO

BACKGROUND: Language has been shown to play a critical role in social cognitive reasoning in preschool and school-aged children, but little research has been conducted with adolescents. During adolescence, the ability to understand figurative language becomes increasingly important for social relationships and may affect social adjustment. This study investigated the contribution of structural and figurative language to social cognitive skills in adolescents who present for mental health services and those who do not. METHOD: One hundred and thirty-eight adolescents referred to mental health centers (clinic group) and 186 nonreferred adolescents (nonclinic group) aged 12-17 were administered measures of structural and figurative language, working memory, and social cognitive problem solving. RESULTS: We found that adolescents in the clinic group demonstrated less mature social problem solving overall, but particularly with respect to anticipating and overcoming potential obstacles and conflict resolution compared with the nonclinic group. In addition, results demonstrated that age, working memory, and structural and figurative language predicted social cognitive maturity in the clinic group, but only structural language was a predictor in the nonclinic group. CONCLUSIONS: Social problem solving may be particularly difficult for adolescents referred for mental health services and places higher demands on their cognitive and language skills compared with adolescents who have never been referred for mental health services.

RESUMO

BACKGROUND: Clinic and community-based epidemiological studies have shown an association between child psychopathology and language impairment. The demands on language for social and academic adjustment shift dramatically during adolescence and the ability to understand the nonliteral meaning in language represented by higher order language becomes essential. OBJECTIVES:  : This article reports on the association between difficulties in higher order language skills, reading, cognition, and social-emotional adjustment in adolescents. METHOD:  : 144 clinic-referred and 186 comparison youth aged 12-18 years were administered a battery of standardized tests of intelligence, working memory, structural and higher order language, and reading achievement. Parent ratings on the Child Behavior Checklist were used as a measure of severity of social-emotional problems. RESULTS:  : Clinic-referred youth scored significantly lower than comparison youth on measures of structural and higher order language, working memory, and reading. Of the clinic-referred youth, 45% had some type of higher order language impairment, whereas this was the case for 15% of youth in the comparison group. Lower levels of nonverbal ability and working memory as well as lower level of mothers' education were associated with greater risk of having higher order language impairment. CONCLUSIONS:  : Findings have implications for practitioners' seeking to understand and treat adolescents since therapeutic techniques rely on skills where higher order language is at play including the ability to discuss opinions flexibly and to weigh interpretations. Therapists must be aware that there are areas that have potential for miscommunication with some adolescents and where inaccurate inferences may be made about their behavior. Furthermore, educators must consider resources for youth who may increasingly struggle in high school because of such difficulties.

RESUMO

Dietary pattern analysis is an epidemiological method designed to consider the complexity of food preferences and diet patterns of populations. Few studies from South Asia have used this methodology to describe population food intake. Our objective was to identify dietary patterns and understand their associations with sociodemographic, anthropometric and life-style factors among low-income Pakistani urban adults. Dietary information was collected by a thirty-three-item FFQ and dietary patterns were derived by principal component analyses in 5491 subjects enrolled in the Control of Blood Pressure and Risk Attenuation (COBRA) study. Three dietary patterns were identified: a fat and sweet pattern characterised by fried snacks/foods, desserts, organ meats, bakery products, Pakistani bread and food purchased from outside the home; a fruit and vegetable pattern including fruits, juices, raw and cooked vegetables, lean meat and low-fat milk; and a seafood and yogurt pattern identified by prawns, fish, potatoes and yogurt. The fat and sweet pattern scores were low among older subjects, those with high BMI and waist circumference but high among females and physically active participants. The fruit and vegetable pattern was associated with younger age, high BMI, education and non-tobacco use. The seafood and yogurt pattern was associated with high BMI, increased physical activity and non-tobacco use. In conclusion, distinct dietary patterns exist for the Pakistani population that may be related to some of the population characteristics and thus may have importance in suggesting dietary and life-style interventions in the prevention of chronic diseases.

RESUMO

OBJECTIVE: To assess how postsecondary online nutrition education courses (ONEC) are delivered, determine ONEC effectiveness, identify theoretical models used, and identify future research needs. DESIGN: Systematic search of database literature. SETTING: Postsecondary education. PARTICIPANTS: Nine research articles evaluating postsecondary ONEC. MAIN OUTCOME MEASURES: Knowledge/performance outcomes and student satisfaction, motivation, or perceptions. ANALYSIS: Systematic search of 922 articles and review of 9 articles meeting search criteria. RESULTS: Little research regarding ONEC marketing/management existed. Studies primarily evaluated introductory courses using email/websites (before 2000), or course management systems (after 2002). None used true experimental designs; just 3 addressed validity or reliability of measures or pilot-tested instruments. Three articles used theoretical models in course design; few used theories to guide evaluations. Four quasi-experimental studies indicated no differences in nutrition knowledge/performance between online and face-to-face learners. Results were inconclusive regarding student satisfaction, motivation, or perceptions. CONCLUSIONS AND IMPLICATIONS: Students can gain knowledge in online as well as in face-to-face nutrition courses, but satisfaction was mixed. More up-to-date investigations on effective practices are warranted, using theories to identify factors that enhance student outcomes, addressing emerging technologies, and documenting ONEC marketing, management, and delivery. Adequate training/support for faculty is needed to improve student experiences and faculty time management.

RESUMO

The objective of this work was to study the newly developed and existing tomato (Lycopersicon esculentum Mill.) varieties for physicochemical changes in the fruits in the ripe period. Varieties 'CXD179' and 'CX8401' in fresh and canned, and 'CXD203' and 'CXD276' in paste were found superior with respect to ascorbic acid and antioxidant capacity. The highest lycopene and beta-carotene contents were determined in 'CXD203', 'CXD276', and 'CX8401'. Color values showed a change from a greenness value of 'a' to redness values, whereas 'b' decreased. In general, parameter values were higher in canned samples. Studies showed that the lycopene content best correlated with 'a' values in the ripening. Inter-variety variation in physicochemical parameters at the ripe stage revealed that 'CXD179' and 'CXD203' in all products among red varieties were the best varieties. Among light color varieties 'CXD276' and 'CX8401' in view of red color, and 'CX8400' and 'CX8402' in view of green color were better.

RESUMO

RNA interference (RNAi) mechanisms are conserved and consist of an interrelated network of activities that not only respond to exogenous dsRNA, but also perform endogenous functions required in the fine tuning of gene expression and in maintaining genome integrity. Not surprisingly, RNAi functions have widespread influences on cellular function and organismal development. Previously, we observed a reduced capacity to mount an RNAi response in nine Caenorhabditis elegans mutants that are defective in ABC transporter genes (ABC(RNAi) mutants). Here, we report an exhaustive study of mutants, collectively defective in 49 different ABC transporter genes, that allowed for the categorization of one additional transporter into the ABC(RNAi) gene class. Genetic complementation tests reveal functions for ABC(RNAi) transporters in the mut-7/rde-2 branch of the RNAi pathway. These second-site noncomplementation interactions suggest that ABC(RNAi) proteins and MUT-7/RDE-2 function together in parallel pathways and/or as multiprotein complexes. Like mut-7 and rde-2, some ABC(RNAi) mutants display transposon silencing defects. Finally, our analyses reveal a genetic interaction network of ABC(RNAi) gene function with respect to this part of the RNAi pathway. From our results, we speculate that the coordinated activities of ABC(RNAi) transporters, through their effects on endogenous RNAi-related mechanisms, ultimately affect chromosome function and integrity.

RESUMO

BACKGROUND: China has become a lead country for international adoption because of the relatively young age of the children and reported positive conditions of the orphanages. This study examined the process and outcome of growth and development of children adopted from China over their first two years with their adoptive families. METHOD: Seventy infant girls adopted from China at 8 to 21 months of age (Mean age = 13 months) were examined on arrival in Canada and 6, 12, and 24 months later. Comparisons were made with non-adopted Canadian girls of similar age and from a similar family background as adoptive parents on indices of growth and standardized measures of mental, psychomotor, and language development. RESULTS: At arrival, children adopted from China were smaller physically and exhibited developmental delays compared to current peers. Children adopted from China were functioning in the average range on physical and developmental measures within the first 6 months following adoption. However, they were not performing as well as current peers until the end of their second year after adoption. Even then, there was developmental variation in relation to comparison children and continuation of relatively smaller size with respect to height, weight, and head circumference. Physical measurement was related to outcomes at various points on all developmental measures. CONCLUSIONS: Deprivation in experience in the first year of life has more long-lasting effects on physical growth than on mental development. The variable most consistently related to development was height-to-age ratio. As a measure of nutritional status, the findings reinforce the critical importance of early nutrition.
