RESUMEN
Food insecurity, poised to increase with burgeoning concerns related to climate change, may influence sleep, yet few studies examined the food security-sleep association among racially/ethnically diverse populations with multiple sleep dimensions. We determined overall and racial/ethnic-specific associations between food security and sleep health. Using National Health Interview Survey data, we categorised food security as very low, low, marginal and high. Sleep duration was categorised as very short, short, recommended and long. Sleep disturbances included trouble falling/staying asleep, insomnia symptoms, waking up feeling unrested and using sleep medication (all ≥3 d/times in the previous week). Adjusting for socio-demographic characteristics and other confounders, we used Poisson regression with robust variance to estimate prevalence ratios (PRs) and 95 % confidence intervals (95 % CIs) for sleep dimensions by food security. Among 177 435 participants, the mean age of 47â 2 ± 0â 1 years, 52â 0 % were women, and 68â 4 % were non-Hispanic (NH)-White. A higher percent of NH-Black (7â 9 %) and Hispanic/Latinx (5â 1 %) lived in very low food security households than NH-White (3â 1 %) participants. Very low v. high food security was associated with a higher prevalence of very short (PR = 2â 61 [95 % CI 2â 44-2â 80]) sleep duration as well as trouble falling asleep (PR = 2â 21 [95 % CI 2â 12-2â 30]). Very low v. high food security was associated with a higher prevalence of very short sleep duration among Asian (PR = 3â 64 [95 % CI 2â 67-4â 97]) and NH-White (PR = 2â 73 [95 % CI 2â 50-2â 99]) participants compared with NH-Black (PR = 2â 03 [95 % CI 1â 80-2â 31]) and Hispanic/Latinx (PR = 2â 65 [95 % CI 2â 30-3â 07]) participants. Food insecurity was associated with poorer sleep in a racially/ethnically diverse US sample.

OBJECTIVE: Childhood adversity has been associated with metabolic syndrome (MetS) and type 2 diabetes risk in adulthood. However, studies have yet to investigate traumatic childhood experiences (TCEs) beyond abuse and neglect (e.g., natural disaster) while considering potential racial/ethnic differences. RESEARCH DESIGN AND METHODS: To investigate race/ethnicity as a potential modifier of the association between TCEs, MetS, and type 2 diabetes, we used prospectively collected data from 42,173 eligible non-Hispanic White (NHW; 88%), Black/African American (BAA; 7%), and Hispanic/Latina (4%) Sister Study participants (aged 35-74 years) enrolled from 2003 to 2009. A modified Brief Betrayal Trauma Survey captured TCEs. At least three prevalent metabolic abnormalities defined MetS, and self-report of a new diagnosis during the study period defined type 2 diabetes. We used adjusted Cox proportional hazards regression to estimate hazard ratios (HRs) and 95% CIs for type 2 diabetes over a mean ± SD follow-up of 11.1 ± 2.7 years, overall and by race/ethnicity. We also tested for modification and mediation by MetS. RESULTS: Incident cases of type 2 diabetes were reported (n = 2,479 among NHW, 461 among BAA, and 281 among Latina participants). Reporting any TCEs (50% among NHW, 53% among BAA, and 51% among Latina participants) was associated with a 13% higher risk of type 2 diabetes (HR 1.13; 95% CI 1.04-1.22). Associations were strongest among Latina participants (HR 1.64 [95% CI 1.21-2.22] vs. 1.09 for BAA and NHW). MetS was not a modifier but mediated (indirect effect, HR 1.01 [95% CI 1.00-1.01]; P = 0.02) the overall association. CONCLUSIONS: TCE and type 2 diabetes associations varied by race/ethnicity and were partially explained by MetS.

Qualitative studies have identified haircare practices as important culturally specific barriers to physical activity (PA) among Black/African American (AA) women, but quantitative investigations are lacking. Using the Study of Environment, Lifestyle and Fibroids data among 1558 Black/AA women, we investigated associations between hair product usage/hair maintenance behaviors and PA during childhood and adulthood. Participants reported childhood and current chemical relaxer and leave-in conditioner use. Self-reported PA included childhood recreational sports participation, leisure-time PA engagement during adulthood, and, at each life stage, minutes of and intensity of PA. Adjusting for socioeconomic and health characteristics, we used Poisson regression with robust variance to estimate prevalence ratios (PRs) and 95% confidence intervals (CIs) for each PA measure for more vs. less frequent hair product use/hair maintenance. Thirty-four percent reported ≥twice/year chemical relaxer use and 22% reported ≥once/week leave-in conditioner use at age 10 years, and neither were associated with PA at age 10 years. In adulthood, ≥twice/year chemical relaxer users (30%) were less likely (PR = 0.90 [95% CI: 0.79-1.02]) and ≥once/week leave-in conditioner users (24%) were more likely (PR = 1.09 [95% CI: 0.99-1.20]) to report intense PA compared to counterparts reporting rarely/never use. Hair product use/maintenance may influence PA among Black/AA women and impact cardiometabolic health disparities.
