Exploring the relationship between sunlight exposure, psychological health, and gestational weight gain: a prospective observational study.

INTRODUCTION: Gestational weight gain (GWG) is influenced by various factors during pregnancy. This study attempts to explore the relationship between environmental factors i.e., sunlight exposure and psychological health i.e. psychological well-being and sleep quality during pregnancy with total gestational weight gain. METHODS: This was a prospective observational study conducted in government maternity clinics in Kuala Lumpur. Pregnant women aged 19-39 years without comorbidities were recruited during second trimester and followed up until birth. The participants were required to wear a UVB dosimeter for a total of three consecutive days (2 weekdays and 1 weekend) to determine sunlight exposure (SED) during their second trimester. The PSQI and DASS-21 were used to determine sleep quality and psychological wellbeing, respectively. GWG data were collected from clinic health records. The association of sun exposure and psychological health with total GWG was determined using multiple linear regression. RESULTS: A total of 73 pregnant women aged 27.9 ± 3.3 years were included in the analysis. The prevalence of pregnant women exhibiting stress, anxiety, and depression symptoms was 11%, 40%, and 16% respectively. The global PSQI median score was 5 (IQR = 3), with 59% having poor sleep quality. Median sleep duration was 7 h (IQR = 2) while median sleep efficiency was 92% (IQR = 14). The median SED was 0.04 (IQR = 0.09), with 51% of them being under the 50th percentile. The majority had adequate GWG (58%). Sleep parameters were not found to be correlated with total GWG except for sleep latency (ρ = -0.356, p = 0.002). Sunlight exposure was found to have no significant relationship with sleep and total GWG. Adjusted multiple linear regression showed that greater depression is associated with higher total GWG (ß = 0.239, p = 0.039) while controlling for sleep quality. CONCLUSION: Depression was associated with total GWG when sleep quality was controlled for while sunlight exposure had no significant association with GWG. Future studies should study the complex relationship between factors of mental health, sleep, and weight gain during pregnancy. Healthcare providers may be better equipped to develop interventions aimed to prevent negative maternal and fetal health outcomes.

Tobacco advertising, promotion, sponsorship and youth smoking behavior: The Indonesian 2019 Global Youth Tobacco Survey (GYTS).

INTRODUCTION: Tobacco advertisement, promotion, and sponsorship (TAPS) in all forms influences youth smoking behaviors. TAPS exposure enhances their smoking frequency and vulnerability. A 2018 Indonesia Ministry of Health (MoH) Survey showed increased smoking prevalence among youth aged 10-18 years. Thus, our objective was to analyze the relationship between TAPS and the increased Indonesian youth smoking behavior. METHODS: We conducted a secondary analysis of the Indonesian 2019 Global Youth Tobacco Survey. The sample size differed in each variable: current smokers n=3386, ever smoker n=3666, and cigarette consumption per day n=1355. We adjusted for socioeconomic and demographic variables and used logistic regression with youth smoking prevalence as the outcome and TAPS variables as the primary exposures. RESULTS: The current male youth smoker prevalence was 38.3%, ever smoker was 67%, and high consumption per day smoker (≥2 cigarettes per day) was 39.1%. Youth respondents exposed to the promotion or sponsorship of cigarette products showed an increase in three smoking behaviors. In particular, when youth respondents were exposed to more than one type of cigarette promotion (AOR=1.67, 95% CI: 1.33-2.09) or noticed one type of cigarette sponsorship (AOR=2.06, 95% CI: 1.44-2.93), their odds of all three smoking behaviors (current smoker, ever smoker, and high consumption smoker) increased. CONCLUSIONS: TAPS increase smoking behaviors among Indonesian youth. Therefore, to protect Indonesian youth health in the future, strategic action is needed to reduce youth smoking by banning all forms of TAPS in Indonesia.

Utilization of Postnatal Care Service in Indonesia and its Association with Women's Empowerment: An Analysis of 2017 Indonesian Demographic Health Survey Data.

OBJECTIVE: The coverage of postnatal care (PNC) is among the lowest globally when compared with other maternal and child interventions. This study aims to assess PNC utilisation in Indonesia and its association with women's empowerment indicators to provide evidence for the need for policy change. METHODS: Data from the 2017 Indonesian Demographic Health Surveys was analyzed for any use of PNC, early first PNC (within 2 days of birth) and PNC after discharge for newborns. Women's empowerment factors were calculated using a principal component analysis of 17 indicators. The association between women's empowerment factors and PNC was assessed using logistic regression adjusted for covariates and complex survey design. RESULTS: The prevalence of any PNC by skilled professionals in Indonesia was high but PNC after discharge was very low. Labor-force participation and women's knowledge level were associated with any PNC, but the association between women's knowledge level and any PNC was modified by place of birth. Disagreement towards justification of wife beating and women's knowledge level were associated with early PNC but the association was modified by place of birth. Decision-making power was also associated with early PNC but modified by infant's gender. Disagreement towards justification of wife beating was negatively associated with PNC after discharge, but the association between decision-making power and PNC after discharge was modified by the infant's size at birth. CONCLUSIONS FOR PRACTICE: PNC coverage after discharge in Indonesia needs improvement. Women's empowerment indicators need to be addressed in improving PNC coverage.

Maternal depression is the predominant persistent risk for child cognitive and social-emotional problems from early childhood to pre-adolescence: A longitudinal cohort study.

RATIONALE: Brain development occurs rapidly during early childhood and continues throughout middle childhood. Early and later windows of opportunity exist to alter developmental trajectories. Few studies in low- and middle-income countries have examined the importance of the timing of exposure to risks for poor pre-adolescent cognitive and social-emotional outcomes. METHODS: We assessed 359 children who participated in two follow-up studies of the Supplementation with Multiple Micronutrients Intervention Trial conducted in Indonesia in 2001-2004: at 3.5 years in 2006 and 9-12 years in 2012-2014. Using structural equation models, we examined indicators of early childhood (3.5 y) and pre-adolescent (9-12 y) exposure to risks (child height-for-age z-score [HAZ], hemoglobin [Hb], maternal depressive symptoms [MDS], home environment [HOME]), with two developmental outcomes: cognitive ability and social-emotional problems. We characterized patterns of change by calculating residuals of indicators measured earlier (3.5 y) predicting the same indicators measured later (9-12 y), for example, the residual of 3.5 y MDS predicting 9-12 y MDS (rMDS). RESULTS: Three early risk indicators (HOME, Hb, and MDS) were indirectly associated with pre-adolescent cognitive scores through early cognitive scores (HOME: 0.15, [95% CI 0.09, 0.21]; Hb: 0.08 [0.04, 0.12], MDS: -0.07 [-0.12, -0.02]). Pre-adolescent cognitive scores were also associated with change in MDS (rMDS: -0.13 [-0.23, -0.02]) and Hb (rHb: 0.10 [0.00, 0.20]) during middle childhood. For pre-adolescent social-emotional problems, both early childhood MDS (0.31 [0.19, 0.44]) and change in MDS during middle childhood (rMDS: 0.48 [0.37, 0.60]) showed strong direct associations with this outcome. CONCLUSIONS: Our findings confirm those of previous studies that prevention of risk exposures during early childhood is likely to support long-term child development. It also adds evidence to a previously scarce literature for the middle childhood period. Prevention of maternal depressive symptoms and child anemia during middle childhood should be assessed for effectiveness to support child development.

Two tobacco retailer programmes in Banyuwangi, Indonesia: a qualitative study.

INTRODUCTION: The tobacco retail density in Indonesia is very high, and tobacco companies are creative at promoting their products at point of sale (POS). The study explores the strategies employed by tobacco companies through their retailer programmes in Banyuwangi, Indonesia. METHODS: In 2019 we conducted observation and indepth interviews with the owners/keepers of 12 retailers with Sampoerna Retail Community (SRC) signs and 6 retailers with Gudang Garam Strategic Partnership signs placed as store names in front of their stores. We analysed the data to identify key strategies used by each tobacco company. RESULTS: Gudang Garam promoted more visibility of their own products, while Sampoerna promoted their products in a power wall and also rearranged other products sold in the store to attract more customers. Sampoerna educated their retailers to attract and retain more customers by using schemes such as reward points and coupons. Sampoerna also developed and promoted the use of a mobile application for online sales. CONCLUSIONS: Both programmes promote product and brand display at retailers to create brand loyalty. The SRC mobile application for online sales is potentially attractive to young customers and allows for data collection about retail and customer purchase behaviours that can be used for tailored marketing. Tobacco sales promotion strategies should be strongly regulated. Banning indoor tobacco advertisement, promotion and tobacco display at POS should be encouraged.

Density of cigarette retailers near schools and sales to minors in Banyuwangi, Indonesia: A GIS mapping.

INTRODUCTION: There are weak regulations and controls on tobacco sales to adolescents in Indonesia, and these may have contributed to the increase in smoking prevalence among adolescents in the country. Our study aims to calculate the density of cigarette retailers near schools and ascertain the factors associated with sales to minors. METHODS: We conducted geographical mapping by recording the GPS position of cigarette retailers in 15 locations in Banyuwangi District, Indonesia, to assess the density and proximity of cigarette retailers to schools. We interviewed randomly selected retailers, from the geographical mapping, for information on sales to minors, the cheapest price cigarettes are sold and the most popular cigarette brand purchased by adolescents, as well as owners/keepers knowledge of the regulation regarding sales to minors. RESULTS: We identified 770 retailers of consumer goods in the study location; 28.1% (216) sold cigarettes, with mean density of 1.1 cigarette retailers per 100 m. Of the cigarette retailers, 6.9% were located <25 m from schools and all schools had at least one retailer within a 250 m radius. Owners/keepers of 107 cigarette retailers agreed to be interviewed for information on sales to minors. Brands from Gudang Garam were the most popular among adolescents and the brand from Bentoel, part of British American Tobacco, was the cheapest. The median of the cheapest price sold was US$0.7 per pack. Only 43.6% of retailers ever refused to sell cigarettes to adolescents. Within a school complex, retailers' refusal to sell cigarettes to adolescents was higher than in other locations. CONCLUSIONS: Schools in Banyuwangi are surrounded by cigarette retailers. Half of the retailers sell cigarettes at a price affordable by adolescents, attracting adolescents to initiate smoking. There needs to be strict regulation to control cigarette sales to minors, through zoning and licensing in Indonesia.

Determinants of age-appropriate breastfeeding, dietary diversity, and consumption of animal source foods among Indonesian children.

Global child feeding practices remain suboptimal. In this study, we assess the determinants of age-inappropriate breastfeeding, dietary diversity, and consumption of 3+ types of animal source foods (ASFs) using 11,687 observations from combined data from the Indonesian Demographic Health Survey of 2012 and 2017. We used linear and logistic regression after adjusting for the complex sampling design. Child's age and quality of antenatal care (ANC) were associated with all outcomes. Socio-economic status and labour force participation were positively associated with higher dietary diversity score, ASF consumption, and age-inappropriate breastfeeding. More ANC visits and having consultation at ANC were associated with more dietary diversity. Higher women's knowledge level was associated with more dietary diversity and consuming more ASF. Compared with western Indonesia, more children in eastern Indonesia were age-inappropriately breastfed and had lower dietary diversity. The Indonesian government needs to develop programmes to improve child feeding particularly in eastern Indonesia, focusing on improving dietary diversity and ASF consumption in poorer households and on prolonging breastfeeding in richer households. Women's labour force participation should be encouraged, but programmes for working mothers are also needed to support continued breastfeeding and to express breast milk. ANC and postnatal programmes need improved consultation sessions for child feeding.

Cigarette retailer density around schools and neighbourhoods in Bali, Indonesia: A GIS mapping.

INTRODUCTION: The presence and density of tobacco retailers is associated with the perception of high availability of cigarettes and ease of purchase. Indonesia is the second largest cigarette market in the world with an increasing smoking rate among young people aged 10-18 years. Our study aims to assess density of cigarette outlets in neighbourhoods and around schools, and to evaluate correlation between retailer proximity to schools and retailer selling practices. METHODS: We conducted a geographical mapping and then an audit survey of 1000 randomly selected cigarette retailers in Denpasar, Bali, Indonesia. We measured neighbourhood retailer density, and retailer proximity to schools. We linked the coordinate data to the audit data to assess the association between retailer distance from schools with likelihood of selling tobacco to young people and selling single cigarette sticks. RESULTS: We mapped 4114 cigarette retailers in Denpasar, the most common type was a kiosk, 3199 (77.8%), followed by mini market/convenience stores, 606 (14.7%). Retailer density was 32.2/km2 and 4.6/1000 population. We found that 37 (9.7 %) of the 379 schools in Denpasar have at least one cigarette retailer within a 25 m radius and 367 (96.8%) within a 250 m radius. Of the 485 audited retailers within a 250 m radius of a school, 281 (57.9%) admitted selling cigarettes to young people and 325 (67.0%) sold cigarettes as single sticks. Cigarette retailers were less likely to sell cigarettes to young people based on distance from schools, but this was only significant at the furthest distance of more than 500 m from schools. CONCLUSIONS: In an unregulated retailer setting such as Indonesia, cigarette retailers are ubiquitous and selling to young people is commonplace. The Indonesian government should enforce the prohibition on selling to young people and should regulate cigarette retailers to reduce youth access to cigarettes.

From glass boxes to social media engagement: an audit of tobacco retail marketing in Indonesia.

OBJECTIVE: To assess tobacco promotion intensity, retailer behaviours and tobacco company efforts to link retailer marketing to online channels. METHODS: We completed an audit of tobacco advertisements and promotions at 1000 randomly selected cigarette retailers in Denpasar, Bali, Indonesia that included an observation checklist, digital photos and structured interviews with retailers. We then calculated the tobacco promotion index for each retailer and made comparisons based on store types. Next, we conducted a photo analysis from 100 randomly selected retailers to explore links to online channels and other promotional cues to engage young people. RESULTS: Mini-markets have both the highest total number of promotions and the highest indoor promotion index with a mean score of 5.1 and 3.7, respectively. Kiosks have the highest outdoor promotion index with a mean score of 1.6. Most of the retailers (98.9%) displayed cigarettes, more than half of kiosk retailers (54.8%) and mini-market retailers (56.3%) admitted selling cigarettes to young people, and 74% of kiosk retailers sell single stick cigarettes. We found links to online marketing, including two hashtags and a company website. Promotional materials also included youth-focused content such as English taglines, new products and small packs. CONCLUSION: Tobacco companies in Indonesia have strategically differentiated their advertisements based on retailer type and have bridged conventional retailer marketing to online channels. Reforming Indonesian tobacco laws to include bans on single sticks and small pack sales, point-of-sale advertising, including displays, and enforcement of laws on sales to minors is urgently required.

Mixed-methods evaluation of a ban on tobacco advertising and promotion in Banyuwangi District, Indonesia.

INTRODUCTION: Tobacco advertisement bans in Indonesia are rare and seldom evaluated. The recent introduction of an outdoor tobacco advertisement (OTA) ban in Banyuwangi District, East Java, Indonesia provided an opportunity to evaluate such policy. METHODS: Using a mixed-methods approach, we undertook an observational study of OTA in 15 locations where such advertising had been prohibited. We also interviewed a sample of 114 store-owners/storekeepers and 131 community members, and conducted indepth interviews with government officials and the Public Order Agency (POA), the designated enforcement agency. RESULTS: In phase 1 we found only one location was free of advertisements. We identified 667 advertisement points and 1283 advertisement materials in the study location; of these, 7% and 7.8% were within 25 m of schools and religious sites, respectively. Phase 2 showed that 68% of the respondents were unaware of the regulation, but many supported an OTA ban. Indepth interviews revealed that not all members of the POA were familiar with the regulation. POA members believed they will enforce the regulation better if higher level regulation for ban on tobacco advertisements, promotions and sponsorships was made and digital application is available to support surveillance. CONCLUSION: Policy violations were evident 1 year after the launch of OTA ban in Banyuwangi. Tobacco advertisements are still visible, including near schools and religious sites, potentially stimulating adolescents to smoke. Regional regulation and setting specific violation reductions as a performance indicator for POA could improve compliance. App-based technology could assist violation surveillance and reporting, as could awareness-raising campaigns that encouraged community support to report violation through the apps.

Maternal multiple micronutrient supplementation and other biomedical and socioenvironmental influences on children's cognition at age 9-12 years in Indonesia: follow-up of the SUMMIT randomised trial.

BACKGROUND: Brain and cognitive development during the first 1000 days from conception are affected by multiple biomedical and socioenvironmental determinants including nutrition, health, nurturing, and stimulation. An improved understanding of the long-term influence of these factors is needed to prioritise public health investments to optimise human development. METHODS: We did a follow-up study of the Supplementation with Multiple Micronutrients Intervention Trial (SUMMIT), a double-blind, cluster-randomised trial of maternal supplementation with multiple micronutrients (MMN) or iron and folic acid (IFA) in Indonesia. Of 27 356 live infants from birth to 3 months of age in 2001-04, we re-enrolled 19 274 (70%) children at age 9-12 years, and randomly selected 2879 from the 18 230 who were attending school at a known location. Of these, 574 children were oversampled from mothers who were anaemic or malnourished at SUMMIT enrolment. We assessed the effects of MMN and associations of biomedical (ie, maternal and child anthropometry and haemoglobin and preterm birth) and socioenvironmental determinants (ie, parental education, socioeconomic status, home environment, and maternal depression) on general intellectual ability, declarative memory, procedural memory, executive function, academic achievement, fine motor dexterity, and socioemotional health. The SUMMIT trial was registered, number ISRCTN34151616. FINDINGS: Children of mothers given MMN had a mean score of 0·11 SD (95% CI 0·01-0·20, p=0·0319) higher in procedural memory than those given IFA, equivalent to the increase in scores with half a year of schooling. Children of anaemic mothers in the MMN group scored 0·18 SD (0·06-0·31, p=0·0047) higher in general intellectual ability, similar to the increase with 1 year of schooling. Overall, 18 of 21 tests showed a positive coefficient of MMN versus IFA (p=0·0431) with effect sizes from 0·00-0·18 SD. In multiple regression models, socioenvironmental determinants had coefficients of 0·00-0·43 SD and 22 of 35 tests were significant at the 95% CI level, whereas biomedical coefficients were 0·00-0·10 SD and eight of 56 tests were significant, indicating larger and more consistent impact of socioenvironmental factors (p<0·0001). INTERPRETATION: Maternal MMN had long-term benefits for child cognitive development at 9-12 years of age, thereby supporting its role in early childhood development, and policy change toward MMN. The stronger association of socioenvironmental determinants with improved cognition suggests present reproductive, maternal, neonatal, and child health programmes focused on biomedical determinants might not sufficiently enhance child cognition, and that programmes addressing socioenvironmental determinants are essential to achieve thriving populations.

Determinants of low birthweight, small-for-gestational-age and preterm birth in Lombok, Indonesia: analyses of the birthweight cohort of the SUMMIT trial.

OBJECTIVE: To examine the determinants of low birthweight (LBW), small-for-gestation (SGA) and preterm births in Lombok, Indonesia, an area of high infant mortality. METHODS: Data from The Supplementation with Multiple Micronutrient Intervention Trial (SUMMIT), a double-blind cluster-randomised controlled trial, were analysed. The odds ratio of factors known to be associated with LBW, SGA and preterm birth was assessed and adjusted for the cluster design of the trial using hierarchical logistic regression. Determinants included constitutional, demographic and psychosocial factors, toxic exposure, maternal nutrition and obstetric history and maternal morbidity during and prior to pregnancy. Population attributable risks of modifiable determinants were calculated. RESULTS: A cohort of 14,040 singleton births was available for analysis of LBW, with 13,498 observations for preterm births and 13,461 for SGA births. Determinants of LBW and SGA were similar and included infant's sex, woman's education, season at birth, mothers' residence, household wealth, maternal mid-upper arm circumference (MUAC), height and a composite variable of birth order and pregnancy interval. Socioeconomic indicators were also related to preterm births and included mother's education, residence and household wealth, while nutritional-related factors including low MUAC and birth order and interval were associated with preterm birth but not maternal height. Nausea was protective of preterm birth, while diarrhoea was associated with higher odds of preterm birth. Oedema during pregnancy was protective of SGA but associated with higher odds of preterm delivery. Around 33%, 13% and 13% of the determinants of LBW, SGA and preterm births were preventable. CONCLUSION: Women's education, maternal nutrition and household wealth and family planning are key factors to improving birth outcomes.
