Impact of a Municipal Policy Restricting Trans Fatty Acid Use in New York City Restaurants on Serum Trans Fatty Acid Levels in Adults.

OBJECTIVES: To estimate the impact of the 2006 policy restricting use of trans fatty acids (TFAs) in New York City restaurants on change in serum TFA concentrations in New York City adults. METHODS: Two cross-sectional population-based New York City Health and Nutrition Examination Surveys conducted in 2004 (n = 212) and 2013-2014 (n = 247) provided estimates of serum TFA exposure and average frequency of weekly restaurant meals. We estimated the geometric mean of the sum of serum TFAs by year and restaurant meal frequency by using linear regression. RESULTS: Among those who ate less than 1 restaurant meal per week, geometric mean of the sum of serum TFAs declined 51.1% (95% confidence interval [CI] = 42.7, 58.3)-from 44.6 (95% CI = 39.7, 50.1) to 21.8 (95% CI = 19.3, 24.5) micromoles per liter. The decline in the geometric mean was greater (P for interaction = .04) among those who ate 4 or more restaurant meals per week: 61.6% (95% CI = 55.8, 66.7) or from 54.6 (95% CI = 49.3, 60.5) to 21.0 (95% CI = 18.9, 23.3) micromoles per liter. CONCLUSIONS: New York City adult serum TFA concentrations declined between 2004 and 2014. The indication of greater decline in serum TFAs among those eating restaurant meals more frequently suggests that the municipal restriction on TFA use was effective in reducing TFA exposure. Public Health Implications. Local policies focused on restaurants can promote nutritional improvements.

The association of trajectories of protein intake and age-specific protein intakes from 2 to 22 years with BMI in early adulthood.

No study has analysed how protein intake from early childhood to young adulthood relate to adult BMI in a single cohort. To estimate the association of protein intake at 2, 11, 15, 19 and 22 years with age- and sex-standardised BMI at 22 years (early adulthood), we used linear regression models with dietary and anthropometric data from a Filipino birth cohort (1985-2005, n 2586). We used latent growth curve analysis to identify trajectories of protein intake relative to age-specific recommended daily allowance (intake in g/kg body weight) from 2 to 22 years, then related trajectory membership to early adulthood BMI using linear regression models. Lean mass and fat mass were secondary outcomes. Regression models included socioeconomic, dietary and anthropometric confounders from early life and adulthood. Protein intake relative to needs at age 2 years was positively associated with BMI and lean mass at age 22 years, but intakes at ages 11, 15 and 22 years were inversely associated with early adulthood BMI. Individuals were classified into four mutually exclusive trajectories: (i) normal consumers (referent trajectory, 58 % of cohort), (ii) high protein consumers in infancy (20 %), (iii) usually high consumers (18 %) and (iv) always high consumers (5 %). Compared with the normal consumers, 'usually high' consumption was inversely associated with BMI, lean mass and fat mass at age 22 years whereas 'always high' consumption was inversely associated with male lean mass in males. Proximal protein intakes were more important contributors to early adult BMI relative to early-childhood protein intake; protein intake history was differentially associated with adulthood body size.

Breastfeeding modifies the impact of diarrhoeal disease on relative weight: a longitudinal analysis of 2-12 month-old Filipino infants.

Undernutrition and diarrhoeal disease are major causes of infant mortality. We investigated the combined roles of breastfeeding and diarrhoea on infant size in 2940 infants from the Cebu Longitudinal Health and Nutrition Survey. The study aimed to assess whether breastfeeding status modified the deficits associated with diarrhoeal disease. The primary exposures were combinations of current breastfeeding status (yes/no), the presence of diarrhoeal disease in previous week (yes/no) and a categorical survey variable (six surveys taken at bimonthly intervals when infants were 2-12 months of age). Relative weight (weight-for-length z-scores), calculated using the WHO growth standards, was estimated using sex-stratified, fixed-effects longitudinal models that also adjusted for energy from complementary foods. Post-estimation Wald tests were conducted to identify subgroup differences in relative weight. Diarrhoea was associated with reduced relative weight in both breastfed and non-breastfed infants of 6-12 months. Diarrhoea-related deficits in relative weight were significantly exacerbated in non-breastfed girls of 6 and 8 months. Importantly, in infants <6 months, being breastfed and having diarrhoea was still associated with greater relative weight compared with being non-breastfed and diarrhoea-free. Breastfeeding emerged as a strong contributor to relative weight in younger infants (<6 months) while diarrhoeal disease strongly contributed to deficits in relative weight in older infants (6-12 months). These findings underscore the importance of breastfeeding for promoting infant nutritional status in infants with or without diarrhoea from birth to 12 months.

Breastfeeding and Protein Intake Influence Body Mass Index from 2 Months to 22 Years in the Cebu Longitudinal Health and Nutrition Survey.

BACKGROUND: Protein intake (PI) may alter adiposity but few studies have explored the age-specific associations of PI with body mass index (BMI). OBJECTIVE: We analyzed how PI and breastfeeding relate to BMI in the CLHNS (Cebu Longitudinal Health and Nutrition Survey), an observational Filipino birth cohort (1983-2005). METHODS: Random-effects longitudinal regression models estimated the association of daily breastfeeding frequency and energy-adjusted PI residuals with concurrent BMI z scores (zBMI) measured bimonthly from 2 to 24 mo (n = 2899), and the association of breastfeeding history and PI residuals with concurrent BMI using 5 surveys from 2 to 22 y (n = 2435). Models included statistical interactions between PI, breastfeeding, age, and energy intake and adjusted for potential confounders. RESULTS: Breastfeeding was associated with higher predicted zBMI at 6 mo (ß: 0.491 SD; 95% CI: 0.422, 0.560) and at 18 mo (ß: 0.114 SD; 95% CI: 0.032, 0.197). Daily breastfeeding frequency contributed to higher predicted zBMI in younger infants and lower predicted zBMI in later infancy. Those with longer breastfeeding history (19 mo) were significantly smaller at age 11 y (in kg/m2; ß: -0.220; 95% CI: -0.342, -0.097) than those with a shorter (4 mo) breastfeeding duration. Total complementary PI was positively associated with predicted zBMI. Complementary animal PI was positively associated with predicted zBMI in nonbreastfed infants. Plant PI was inversely associated with predicted zBMI of nonbreastfed infants at 6 mo. At 22 y contrasts between high (75th percentile) and low (25th percentile) PIs showed that animal PI was associated with higher predicted BMI (ß: 0.187; 95% CI: 0.045, 0.329), and total PI was inversely related to predicted BMI (ß: -0.008; 95% CI: -0.015, -0.001). CONCLUSION: Breastfeeding frequency, breastfeeding history, and PI contribute to BMI from infancy to young adulthood in the CLHNS.

The association of nutrition behaviors and physical activity with general and central obesity in Caribbean undergraduate students / Asociación de los comportamientos nutricionales y la actividad física con la obesidad general y central en estudiantes de pregrado del Caribe

Objective. To quantify the prevalence of obesity and obesity-related factors in a crosssectional,observational study of Caribbean students using the results of three recent surveys of health behavior among undergraduates in Barbados, Grenada, and Jamaica. Methods. A total of 1 578 Caribbean undergraduate students from Barbados, Grenada, and Jamaica (ages 18–30 years) completed questionnaires and had physical measurements recorded. Multivariable logistic regression was used to estimate odds ratios (ORs) for the association of nutrition behaviors with prevalence of obesity (body mass index ≥ 30 kg/m2); elevated waist-toheight ratio (W/ht) (> 0.50); and high waist circumference (WC) (> 88 cm in females, > 102 cm in males). Models were adjusted for age, year in university, socioeconomic status, and sex. Results. There was a higher prevalence of obesity (13% versus 10%), high WC (21% versus 7%), and high W/ht (35% versus 25%) in females relative to males. Compared to females, males had reduced odds of obesity (OR 0.46), high WC (OR 0.22), and high W/ht (OR 0.61) (P < 0.05 for all). Both females (46%) and males (24%) reported high levels of physical inactivity. Fruit and vegetable consumption was low (approximately two servings per day). Many students reported avoiding fatty foods (40%); this behavior was associated with high W/ht (OR 1.68), obesity (OR 1.90), and high WC (OR 1.82) (P < 0.05 for all). Irregular breakfast consumption, age, and year of study were also positively associated with obesity. Physical activity was not significantly associated with any obesity measure. Conclusions. There was a low prevalence of healthy behaviors and a high prevalence of obesity in this sample of Caribbean young adults.

The interactive association of dietary diversity scores and breast-feeding status with weight and length in Filipino infants aged 6-24 months.

OBJECTIVE: To assess how breast-feeding and dietary diversity relate to infant length-for-age Z-score (LAZ) and weight-for-age Z-score (WAZ). DESIGN: Breast-feeding, dietary and anthropometric data from the Cebu Longitudinal Health and Nutrition Survey were analysed using sex-stratified fixed-effects longitudinal regression models. A dietary diversity score (DDS) based on seven food groups was classified as low (<4) or high (≥ 4). The complementary feeding patterns were: (i) non-breast-fed with low DDS (referent); (ii) breast-fed with low DDS; (iii) non-breast-fed with high DDS; and (iv) breast-fed with high DDS (optimal). Interactions between age, energy intake and complementary feeding patterns were included. SETTING: Philippines. SUBJECTS: Infants (n 2822) measured bimonthly from 6 to 24 months. RESULTS: Breast-feeding (regardless of DDS) was significantly associated with higher LAZ (until 24 months) and WAZ (until 20 months). For example, at 6 months, breast-fed boys with low DDS were 0.246 (95% CI 0.191, 0.302) sd longer and 0.523 (95% CI 0.451, 0.594) sd heavier than the referent group. There was no significant difference in size between breast-fed infants with high v. low DDS. Similarly, high DDS conferred no advantage in LAZ or WAZ among non-breast-fed infants. There were modest correlations between the 7-point DDS and nutrient intakes but these correlations were substantially attenuated after energy adjustment. We elucidated several interactions between sex, age, energy intake and complementary feeding patterns. CONCLUSIONS: These results demonstrate the importance of prolonged breast-feeding up to 24 months. The DDS provided qualitative information on infant diets but did not confer a significant advantage in LAZ or WAZ.
