The aim of this study was to estimate the prevalence of experimental alcohol intake and associated factors in early adolescence. The overall sample consisted of 4,452 adolescents (mean age = 11.3 years; SD = 0.3) from the 1993 birth cohort in Pelotas, Rio Grande do Sul State, Brazil. Experimental use of alcohol was reported by 17.5% of the interviewees (95%CI: 16.3-18.6), and 5% reported having tried alcohol at nine years of age or younger. Prevalence of experimental alcohol use was higher among adolescents whose mothers had consumed alcohol during pregnancy, whose parents consumed alcohol, who worked outside the home themselves, and who had ever tried smoking. Family strife, parental alcohol intake, and adolescent smoking were strong predictors of experimental alcohol use in early adolescence. Special attention should be targeted to these groups in order to avoid heavy and premature alcohol use in early adolescence.

Prospective Birth Cohort Study

The aim of this study was to evaluate the association between size at birth (birthweight and birth length) and height in early adolescence in a prospective birth cohort study in Pelotas, Rio Grande do Sul, Brazil. Interviews were carried out in 1993, including measurements of birthweight and length, and in 2004-2005, including measurements of weight and height. This analysis includes 4,452 individuals, with a mean age of 11.3 years (standard deviation - SD = 0.3), representing a follow-up rate of 87.5%. Mean height at 11 years was 145.8 cm (SD = 7.9), or 144.9 cm (SD = 7.7) in boys and 146.8 cm (SD = 7.9) in girls. Birthweight and birth length were positively associated with height in early adolescence in the crude analysis, but after adjustment for confounding and for each other, only the effect of birth length was still significant. A one z-score increase in birth length was associated with a 1.63 cm increase in height at 11 years. The present study shows that birth length is a strong predictor of later height, while the effect of birth weight disappears after adjustment for birth length.

The aim of this study was to estimate the prevalence of sedentary behavior and investigate associated factors in adolescents 11 years of age from the 1993 birth cohort in Pelotas, Rio Grande do Sul State, Brazil. Sedentary behavior was investigated with a questionnaire, and was defined as spending more than two hours per day watching television, playing videogames, or using the computer. Of the 4,452 adolescents interviewed, 98% reported watching television, 44% playing videogames, and 22% using the computer. The average time spent on each of these electronic media was 197, 36, and 17 minutes per day, respectively. Prevalence of sedentary behavior was 79.7% (95%CI: 78.6; 80.9) and showed a positive association with socioeconomic level and nutritional status and a negative association with well-being. These 11-year-olds spent extensive time at TV viewing, videogames, and the computer. Special attention should be given to the most exposed groups of adolescents, including the more affluent, overweight, and those with limited schooling.

Maternal Depressive Symptoms

Abstract Background This longitudinal study explored the relationship between trajectories of maternal depressive symptoms and offspring’s risk behavior in adolescence contributing to an extremely scarce literature about the impacts of maternal depression trajectories on offspring risk behaviors. Methods We included 3437 11-year-old adolescents from the 2004 Pelotas Birth Cohort Study. Trajectories of maternal depressive symptoms were constructed using Edinburgh Postnatal Depression Scale (EDPS) from age 3 months to 11 years. We identified five trajectories of maternal depressive symptoms: “low” “moderate low”, “increasing”, “decreasing”, and “chronic high”. The following adolescent outcomes were identified via self-report questionnaire and analyzed as binary outcome –yes/no: involvement in fights and alcohol use at age 11. We used logistic regression models to examine the effects of trajectories of maternal depressive symptoms on offspring’s risk behavior adjusting for potential confounding variable. Results Alcohol use and/or abuse as well as involvement in fights during adolescence, were not significantly associated with any specific trajectory of maternal depressive symptoms neither in the crude nor in the adjusted analyses. Conclusion Alcohol use and involvement in fights at age 11 were not associated with any specific trajectory of maternal depression.

Abstract BackgroundEvidence for Better Lives Study (EBLS) is an endeavour to establish a global birth cohort with participants from resource poor settings across the globe. It aims to investigate mediators and moderators of child development and wellbeing; it envisages informing policy and practice change to promote child health and wellbeing globally. Pakistan is one of the resource poor settings taking part in this global birth cohort; we report the feasibility of establishing such a birth cohort in Pakistan.MethodFrom March 2019 to July 2019, 153 third trimester pregnant women were identified, using community health worker registers, and approached for baseline demographics and a number of maternal wellbeing, mental health, support related information and stress related biomarkers in a peri-urban area of Islamabad Capital Territory. From October 2019 to December 2019, we re-contacted and followed 121 between 8-24 weeks postnatal period. All interviews were done after consent and data was collected electronically. Results150 (98%) third trimester pregnant women consented and were interviewed, 111 (74%) provided bio-samples and 121 (80.6%) were followed up postnatally. Their mean age and years of schooling was 27.29 (5.18) and 7.77 (4.79) respectively. Majority (82.3%) of the participants were housewives. Nearly a tenth were first time mothers while 63% of women reported current pregnancy to have been unplanned. Overall wellbeing and mental health were reported to be poor (WHO-5 mean scores 49.41 (32.20) & PHQ-9 mean scores 8.23 (7.0)). About 22% of women reported four or more adverse childhood experiences; 12.2% reported intimate partner violence during their current pregnancy. During the postnatal follow up visits, 58% of the women reported breastfeeding their infants. ConclusionThe study demonstrated Pakistan site could identify, approach, interview and follow up women and children postnatally, with a high response rates for both the follow up visits and bio-samples. Thus, a larger scale pregnancy birth cohort study in Pakistan is feasible to conduct.

PurposeMaternal and Child Health and Nutrition in Acre, Brazil (MINA-Brazil) is a longitudinal, prospective population-based birth cohort, set-up to understand the effects of early environmental exposures and maternal lifestyle choices on growth and development of the Amazonian children.ParticipantsMother–baby pairs (n=1246) were enrolled at delivery from July 2015 to June 2016 in Cruzeiro do Sul, Acre, Brazil. Mothers of 43.7% of the cohort were recruited in the study during pregnancy from February 2015 to January 2016. Study visits took place during pregnancy, delivery, at 1 month, 6 months, 1 year and 2 years after delivery. In addition to clinical and epidemiological data, samples collected by the MINA-Brazil study include plasma, serum and extracted DNA from blood and faeces, which are stored in a biobank.Findings to dateKey baseline reports found a high prevalence of gestational night blindness (11.5%; 95% CI 9.97% to 13.25%) and maternal anaemia (39.4%; 95% CI 36.84% to 41.95%) at delivery. Antenatal malaria episodes (74.6% ofPlasmodium vivax) were diagnosed in 8.0% of the women and were associated with an average reduction in birth weight z-scores of 0.35 (95% CI 0.14 to 0.57) and in birth length z-scores of 0.31 (95% CI 0.08 to 0.54), compared with malaria-free pregnancies. At 2-year follow-up, data collection strategies combined telephone calls, WhatsApp, social media community and home visits to minimise losses of follow-up (retention rate of 79.5%).Future plansA 5-year follow-up visit is planned in 2021 with similar interviews and biospecimens collection. The findings from this prospective cohort will provide novel insights into the roles of prenatal and postnatal factors in determining early childhood development in an Amazonian population.
