Association of DASH and Depressive Symptoms with BMI over Adulthood in Racially and Socioeconomically Diverse Adults Examined in the HANDLS Study.

ABSTRACT: Adherence to the Dietary Approaches to Stop Hypertension (DASH) diet is linked to slower weight gain over time. Elevated depressive symptoms may lead to poor quality diets, potentially increasing Body Mass Index (BMI). This study explored these pathways using longitudinal data extracted from 1201-1458 Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study participants. DASH mean score was computed using four 24 h recalls [visits(v)1 + v2/2: 2004-2013] and depressive symptoms using the Center for Epidemiologic Studies Depression (CES-D) scale (v1 + v2/2: 2004-2013). BMI was measured at v2: 2009-2013 and v3: 2013-2017. Multiple linear mixed regression and mediation modeling were conducted, linking CES-D(mean) and DASH(mean) to BMI [v2 and annualized change ?BMI (v3-v2)] and exploring mediation of the CES-D(mean)-BMI(v3) and DASH(mean)-BMI(v3) associations through DASH(mean) and CES-D(mean), respectively. Models were further stratified by sex, race and poverty status. Inverse cross-sectional and longitudinal relationships of DASH(mean) with BMI(v2) and ?BMI were detected, mainly in women and <125% of poverty participants. CES-D(mean) was not associated with BMI(v3); no mediation was detected through DASH(mean) in all socio-demographic strata. Moreover, the inverse DASH(mean)-BMI(v3) total effect was not mediated through CES-D(mean). Future studies should explore other pathways aside from depressive symptoms by which DASH can have a preventive effect on weight status over time.

Project description:ObjectiveTo determine the associations between screen media use and sleep throughout infancy (3-12 months).DesignProspective Nurture birth cohort.SettingNorth Carolina, USA, 2013-2015.ParticipantsWomen enrolled in their second to third trimester, completed a phone interview after birth, and completed home visits at 3, 6, 9 and 12 months post partum.Primary and secondary outcome measuresWomen reported the usual hours their infants slept during the day and night and their infants' usual use of five screen media activities at 3, 6, 9 and 12 months post partum. Adjusted mixed-effects regression analyses modelled the associations between infant screen time and sleep outcomes while disaggregating the between-infant and within-infant effects.ResultsAmong 558 mother-infant dyads, 374 (67.0%) infants were black and 304 (54.5%) households earned <$20 000 per year. Half (254, 50.2%) of the infants engaged with screens at 3 months of age, while 326 (72.9%) engaged at 12 months. The median value of the average daily screen time over the study period was 50 (IQR: 10-141) min. Infant screen time was inversely associated with night-time sleep duration only when considering between-infant effects (adjusted beta: -2.9; 95% CI -5.9 to 0.0; p=0.054 for log-transformed screen time). Effects were stronger for television+DVD viewing specifically (adjusted beta: -5.2; 95% CI -9.1 to -1.4; p<0.01 for log-transformed television+DVD time). For example, an infant who averaged 1 hour of television+DVD viewing over the study period slept, on average, 9.20 (95% CI 9.02 to 9.37) hours per night by 12 months compared with 9.60 (95% CI 9.41 to 9.80) hours per night for an infant with no screen time over the study period. There were no significant within-infant effects between screen time and night-time sleep, and screen time was not associated with daytime sleep or night-time awakenings.ConclusionsScreen time during infancy was inversely associated with night-time sleep duration; however, causal associations remain uncertain.Trial registration numberNCT01788644.
