WIC Participation and Attenuation of Stress-Related Child Health Risks of Household Food Insecurity and Caregiver Depressive Symptoms

To examine how family stressors (household food insecurity and/or caregiver depressive symptoms) relate to child health and whether participation in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) attenuates stress-related child health risks. Cross-sectional family stress and cumulative stress models from January 1, 2000, through December 31, 2010. Families recruited from emergency departments and/or primary care in Baltimore, Boston, Little Rock, Los Angeles, Minneapolis, Philadelphia, and Washington, DC. Participants included 26,950 WIC-eligible caregivers and children younger than 36 months; 55.2% were black, 29.9% were Hispanic, and 13.0% were white. Caregivers' mean age was 25.6 years; 68.6% were US-born, 64.7% had completed high school, 38.0% were married, and 36.5% were employed. Of the participants, 24.0% had household food insecurity and 24.4% had depressive symptoms; 9.1% had both stressors, 29.9% had 1 stressor, and 61.0% had neither; 89.7% were WIC participants. Caregivers reported child health, lifetime hospitalizations, and developmental risk. Weight and length were measured. We calculated weight-for-age and length-for-age z scores and the risk of underweight or overweight. The well-child composite comprised good/excellent health, no hospitalizations, no developmental risk, and neither underweight nor overweight. In multivariate analyses adjusted for covariates, as stressors increased, odds of fair/poor health, hospitalizations, and developmental risk increased and odds of well-child status decreased. Interactions between WIC participation and stressors favored WIC participants over nonparticipants in dual stressor families on 3 child health indicators: (1) fair/poor health: WIC participants, adjusted odds ratio (aOR), 1.89 (95% CI, 1.66-2.14) vs nonparticipants, 2.35 (2.16-4.02); (2) well-child status: WIC participants, 0.73 (0.62-0.84) vs nonparticipants, 0.34 (0.21-0.54); and (3) overweight: WIC participants, 1.01 (0.88-1.16) vs nonparticipants, 1.48 (1.04-2.11) (P = .06). As stressors increased, child health risks increased. WIC participation attenuates but does not eliminate child health risks.

Exploring and Reducing Stress in Young Restaurant Workers: Results of a Randomized Field Trial

Young adult restaurant workers face the dual stressors of work adjustment and managing personal responsibilities. We assessed a new psychosocial/health promotion training designed to reduce these stressors in the context of restaurant work. DESIGN . A cluster-randomized trial of a training program, with surveys administered approximately 2 weeks before training and both 6 and 12 months after training. A national restaurant chain. A total of 947 restaurant workers in 28 restaurants. Personal stress, exposure to problem coworkers, and personal and job characteristics. Team Resilience (TR) is an interactive program for stress management, teamwork, and work-life balance. TR focuses on "five Cs" of resilience: compassion, commitment, centering, community, and confidence. ANALYSIS . Mixed-model (multilevel) analysis of covariances. Compared with workers in control stores, workers in TR-trained stores showed significant reductions over time in exposure to problem coworkers (F[2, 80.60] = 4.48; p = .01) and in personal stress (F[2, 75.28] = 6.12; p = .003). The TR program may help young workers who face the challenges of emerging adulthood and work-life balance.

Heavy oil exposure induces high moralities in virus carrier Japanese flounder Paralichthys olivaceus

The relationship between chemical exposure and disease outbreak in fish has not been fully defined due to the limitations of experimental systems (model fish and pathogens). Therefore, we constructed a system using the Japanese flounder, Paralichthys olivaceus, and viral haemorrhagic septicemia virus (VHSV), and evaluated it by heavy oil (HO) exposure. The fish were exposed to HO at 0.3, 0.03, 0.003, and 0g/L following VHSV infection at doses of 102.5 or 103.5 tissue culture infectious dose (TCID)50/fish. As a result, groups given the dual stressors showed more than 90% mortality. Although VHSV infection at 102.5 and 103.5 TCID50/fish without HO exposure also induced high mortality, at 68.8% and 81.3%, respectively, HO exposure induced faster and higher mortality in the virus carrier fish, indicating that chemical stressors raise the risk of disease outbreak in fish. The experimental system established in this study could be useful for chemical risk assessment.
