Is the number of siblings associated with dietary patterns in adolescents? The 1993 birth cohort of Pelotas (Brazil).

ABSTRACT: Our study aimed to estimate the association between number of siblings and dietary patterns in adolescents. Prospective longitudinal study was developed using data from the birth cohort of the city of Pelotas, Brazil, which included 5249 participants. At the 18-year-old follow-up, from 4563 individuals located, 4106 were interviewed (follow-up rate 81.3%). Of these, 3751 were included in our principal component analysis of dietary patterns. Regular dietary intake of 45 food groups over the previous year was measured with a food frequency questionnaire. We identified four patterns, which accounted for 40% of the total variance in food group consumption. These were labeled "Protein and fast food", "Fruit and vegetables", "Common Brazilian", and "Sweets, soft drinks, and dairy products". Crude and adjusted analyses of the association between number of siblings and dietary patterns were performed using linear regression. The number of siblings was positively associated with a higher adherence to each dietary pattern, with the exception of the "Common Brazilian" patterns, for which there was no apparent relationship with number of siblings. The findings showed that a greater number of siblings is related to a more diverse diet in the later adolescence, which may predict better nutrient adequacy and health outcomes.

Project description:Evidence regarding the deleterious effects of diet on blood lipids in adolescence has been inconsistent, and few studies have investigated this association using a dietary pattern approach. We examined whether dietary pattern of adolescents are associated with blood lipid concentrations.Cross-sectional analysis of 3524 18-year-old participants in the 1993 Pelotas (Brazil) Birth Cohort Study. A semi-quantitative food frequency questionnaire was administered. Dietary patterns were established using principal component analysis and analysed as tertiles of factor scores. Independent associations between each dietary pattern tertile and blood lipid values (total cholesterol, LDL-cholesterol, HDL-cholesterol and triglycerides) were tested using adjusted linear regression models stratified by sex. Triglycerides were log-transformed due to their skewed distribution, and the beta coefficients should be interpreted as the % change (increase or decrease).Four dietary patterns were derived: Meat Products and Fast Foods; Fruits and Vegetables; Candies, Sodas and Dairy Products; and Common Brazilian Foods. In the adjusted models, which compared the highest and lowest tertiles of dietary pattern scores, we observed that among girls: 1) the third tertile of the Meat Products and Fast Foods pattern was associated with 1.5 mg/dL (95% CI -3.05; ?-0.04) lower HDL-cholesterol; 2) the second and third tertile of the Candies, Sodas and Dairy Products pattern was associated with 5% and 10% higher triglycerides (? 1.05, 95% CI 1.01; 1.09, ? 1.10, 95% CI 1.05; 1.16), respectively; 3) the second and third tertiles of the Common Brazilian Foods pattern were associated with 4 mg/dL (? -?4.30, 95% CI -7.75; ?-0.85, ? -?4.95, 95% CI -8.53; ?-1.36, respectively) lower total cholesterol and 6% lower triglycerides (? 0.94, 95% CI 0.90; 0.99, ? 0.93, 95% CI 0.89; 0.98, respectively). For boys, 4) the third tertile of the Common Brazilian Foods was associated with 4.6 mg/dL (95% CI -7.91; ?-1.37) lower total cholesterol and 3.8 mg/dL (95% CI -6.51; -?1.13) lower LDL-cholesterol.Dietary patterns were more closely associated with blood lipids among girls than boys at age 18. Higher scores for the Common Brazilian Foods pattern were associated with lower total cholesterol in both sexes.

Project description:PurposeBrazilian society is characterized by deep socioeconomic inequalities. Using data from a population-based birth cohort, we explored how the intersectionality of family income and gender may affect adolescent health and behavioral outcomes.MethodsChildren born in 1993 in the Brazilian city of Pelotas have been followed up prospectively at the age of 15 years when the follow-up rate was 85.7% of the original cohort. Participants answered standardized questionnaires, and anthropometric measures were obtained. Outcomes in five domains were studied: overweight (body mass index above +1 SD of the World Health Organization standard for age and sex), cigarette smoking (in the previous month), violence (fight in which someone was injured, in the past year), self-reported unhappiness (based on a face scale), and psychological symptoms (Strengths and Difficulties Questionnaire). Monthly family income was recoded in quintiles.ResultsResults were available for more than 4,101-4,334 adolescents, depending on the outcome. Overweight was more common among boys than girls (29.7% and 25.6%; p = .004) and was directly related to family income among boys (p < .001), but not among girls (p = .681). Smoking was less common among boys than girls (12.3% and 21.0%, p < .001) and showed strong inverse association with income among girls (p < .001), but not among boys (p = .099). Reported violence was twice as common among boys than girls (16.4% vs. 8.0%; p < .001); an inverse association with income was present among girls (p < .001), but not for boys (p = .925). Boys and girls were similarly likely to report being unhappy (18.4% and 20.1%; p = .176), with an inverse association with family income in girls. Psychological symptoms were slightly less common among boys than girls (25.3% and 28.3%; p = .014), with strong inverse associations with income in both sexes (p < .001). Adolescent girls from poor families were the group with the highest prevalence for three of the five outcomes: smoking, unhappiness, and psychological problems.ConclusionsGender norms influence adolescent health and behavioral outcomes, but the direction and strength of the associations are modified by socioeconomic position. Preventive strategies must take into account the intersectionality of gender and wealth.
