Breastfeeding Discontinuation Not Associated with Maternal Pregravid BMI But Associated with Native Hawaiian or Other Pacific Islander Race in Hawaii and Puerto Rico WIC Participants.

ABSTRACT: Objectives This study investigated the association between maternal pregravid body mass index (BMI) and breastfeeding discontinuation at 4-6 months postpartum in Hawaii and Puerto Rico participants from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Methods A secondary data analysis was conducted from a text message-based intervention in WIC participants in Hawaii and Puerto Rico. The analysis included 87 women from the control group who initiated breastfeeding and whose breastfeeding status was known at the end of the study when infants were 4-6 months old. Pregravid BMI and breastfeeding discontinuation were assessed using questionnaires. Results The association between pregravid BMI and breastfeeding discontinuation was not significant in the unadjusted model or in the adjusted model. Native Hawaiian or Other Pacific Islander (NHOPI) participants showed significantly increased odds of discontinuing breastfeeding (adjusted odds ratio [AOR] 7.12; 95% CI 1.34, 37.97; p?=?.02) compared to all the other racial/ethnic participants, as did older women ages 32-39 years versus women who were 25-31 years old (AOR 4.21; 95% CI 1.13, 15.72; p?=?.03). Women who took vitamins while breastfeeding had decreased odds of discontinuing breastfeeding (AOR 0.15; 95% CI 0.05, 0.46; p?=?.0009). Conclusions for Practice Pregravid BMI was not significantly associated with breastfeeding discontinuation at 4-6 months postpartum in women from Hawaii and Puerto Rico WIC, but NHOPIs and women who were older had higher odds of discontinuing breastfeeding. The results of this study may inform strategies for breastfeeding promotion and childhood obesity prevention but should be further investigated in larger studies.

Project description:A photochemical model platform for Hawaii, Puerto Rico, and Virgin Islands predicting O3, PM2.5, and regional haze would be useful to support assessments relevant for the National Ambient Air Quality Standards (NAAQS), Regional Haze Rule, and the Prevention of Significant Deterioration (PSD) program. These areas have not traditionally been modeled with photochemical transport models, but a reasonable representation of meteorology, emissions (natural and anthropogenic), chemistry, and deposition could support air quality management decisions in these areas. Here, a prognostic meteorological model (Weather Research and Forecasting) and photochemical transport (Community Multiscale Air Quality) model were applied for the entire year of 2016 at 27, 9, and 3 km grid resolution for areas covering the Hawaiian Islands and Puerto Rico/Virgin Islands. Model predictions were compared against surface and upper air meteorological and chemical measurements available in both areas. The vertical gradient of temperature, humidity, and winds in the troposphere was well represented. Surface layer meteorological model performance was spatially variable, but temperature tended to be underestimated in Hawaii. Chemically speciated daily average PM2.5 was generally well characterized by the modeling system at urban and rural monitors in Hawaii and Puerto Rico/Virgin Islands. Model performance was notably impacted by the wildfire emission methodology. Model performance was mixed for hourly SO2, NO2, PM2.5, and CO and was often related to how well local emissions sources were characterized. SO2 predictions were much lower than measurements at monitors near active volcanos on Hawaii, which was expected since volcanic emissions were not included in these model simulations. Further research is needed to assess emission inventory representation of these areas and how microscale meteorology influenced by the complex land-water and terrain interfaces impacts higher time resolution performance.

Project description:Background:Excessive gestational weight gain and rapid infancy weight gain (RIWG) are associated with increased susceptibility to childhood obesity. Since low-income and minority children are particularly at risk, investigation of the associations between gestational weight gain and rate of infancy weight gain may inform childhood obesity prevention. This study investigated the associations between gestational weight gain and rate of infancy weight gain during the first four to six months postpartum in participants from the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Hawai'i and Puerto Rico. Methods:This was a cross-sectional secondary data analysis from a text message-based intervention in WIC participants in Hawai'i and Puerto Rico. The analysis included 80 mother/infant pairs from the control group who completed the follow-up visit when infants were four to six months old. Maternal weight, height, and gestational weight gain were self-reported. Infant weight was measured at baseline and follow-up. A proportional odds model was used to investigate the association between gestational weight gain and infancy weight gain rate (rapid or extremely rapid, on-track, or slow), adjusting for maternal age, pregravid body mass index (BMI) status, parity, and being up-to-date with infant vaccinations. Results:In comparison to recommended gestational weight gain, excessive and inadequate (under the recommended amount) gestational weight gain was associated with 77% decreased (adjusted odds ratio [AOR]?=?0.23; 95% confidence interval [CI]?=?0.08, 0.70; p?=?0.01) and 71% decreased (AOR?=?0.29; 95% CI?=?0.09, 0.94; p?=?0.04) odds of RIWG versus on-track or slow infant weight gain, respectively. In comparison to women with one child, women with two children (AOR?=?0.31; 95% CI?=?0.11, 0.87; p?=?0.03) or three or four children (AOR?=?0.24; 95% CI?=?0.07, 0.88; p?=?0.03) had significantly lower odds of RIWG versus on-track or slow infancy weight gain. Conclusions:Women with excessive or inadequate gestational weight gain had lower proportional odds of RIWG and were more likely to have slower infant weight gain than women who gained the recommended amount of weight.
