Background-We examined the prevalence of depressive symptoms in Barbadian youth with histories of infantile malnutrition and in a healthy comparison group and the extent to which the effect of malnutrition was mediated/moderated by maternal depression.
OBJECTIVES
Insomnia is reported to be more prevalent in minority racial/ethnic groups. Little is known, however, about racial/ethnic differences in changes in insomnia severity over time, particularly among older adults. We examined racial/ethnic differences in trajectories of insomnia severity among middle-aged and older adults.
DESIGN
Data were drawn from five waves of the Health and Retirement Study (2002–2010), a nationally representative longitudinal biennial survey of adults aged >50.
SETTING
Population-based.
PARTICIPANTS
22,252 participants from non-Hispanic white, non-Hispanic black, Hispanic, and other racial/ethnic groups.
INTERVENTION
N/A
MEASUREMENTS
Participants reported the severity of four insomnia symptoms; summed scores ranged from 4 (no insomnia) to 12 (severe insomnia). We assessed change in insomnia across the five waves as a function of race/ethnicity.
RESULTS
Across all participants, insomnia severity scores increased 0.19 points (95% CI=0.14, 0.24; t=7.52; design df=56; p<0.001) over time after adjustment for gender, race/ethnicity, education, and baseline age. After adjusting for the number of accumulated health conditions and BMI, this trend decreased substantially and even changed direction (B=−0.24; 95% CI=−0.29, −0.19; t=−9.22; design df=56; p<0.001). The increasing trajectory was significantly more pronounced in Hispanics compared to non-Hispanic whites, even after adjustment for number of accumulated health conditions, BMI, and number of depressive symptoms.
CONCLUSIONS
Although insomnia severity increases with age—largely due to the accumulation of health conditions—this trend appears more pronounced among Hispanic older adults than in non-Hispanic whites. Further research is needed to determine the reasons for a different insomnia trajectory among Hispanics.
BackgroundMaternal depressive symptoms are negatively associated with early child growth in developing countries; however, few studies have examined this relation in developed countries or used a longitudinal design with data past the second year of the child’s life. We investigated if and when early maternal depressive symptoms affect average growth in young children up to age 6 in a nationally representative sample of US children.MethodsUsing data from 6,550 singleton births from the Early Childhood Longitudinal Study -- Birth Cohort (ECLS-B), we fit growth trajectory models with random effects to examine the relation between maternal depressive symptoms at 9 months based on the twelve-item version of the Center for Epidemiologic Studies Depression Scale (CES-D) and child height and body mass index (BMI) to age 6 years.ResultsMothers with moderate/severe depressive symptoms at 9 months postpartum had children with shorter stature at this same point in time [average 0.26 cm shorter; 95% CI: 5 cm, 48 cm] than mothers without depressive symptoms; children whose mothers reported postpartum depressive symptoms remained significantly shorter throughout the child’s first 6 years.ConclusionsResults suggest that the first year postpartum is a critical window for addressing maternal depressive symptoms in order to optimize child growth. Future studies should investigate the role of caregiving and feeding practices as potential mechanisms linking maternal depressive symptoms and child growth trajectories.
Objective
To determine the association between personality domains and 11-year cognitive decline in a sample from a population-based study.
Method
Data from Waves 3 (1993–1996) and 4 (2003–2004) of the Baltimore cohort of the Epidemiologic Catchment Area (ECA) study were used for analyses. The sample included 561 adults (mean age ±SD = 45.2 ±10.78 years) who completed the NEO Personality Inventory-Revised (NEO PI-R) prior to Wave 4. Participants also completed the Mini-Mental State Examination (MMSE) and immediate and delayed word recall tests at Wave 3, and at Wave 4 10.9 ±0.6 years later.
Results
In models adjusted for baseline cognitive performance, demographic characteristics, medical conditions, depressive symptoms, and psychotropic medication use, each 10-point increase in Neuroticism T-scores was associated with a 0.15-point decrease in MMSE scores (B = −0.15 95% confidence interval (CI) −0.30, −0.01), whereas each 10-point increase in Conscientiousness T-scores was associated with a 0.18-point increase on the MMSE (B = 0.18, 95% CI 0.04, 0.32) and a 0.21-point increase in immediate recall (B = 0.21, 95% CI 0.003, 0.41) between baseline and follow-up.
Conclusion
Findings suggest that greater Neuroticism is associated with decline, and greater Conscientiousness is associated with improvement in performance on measures of general cognitive function, and memory in adults. Further studies are needed to determine the extent to which personality traits in midlife are associated with clinically significant cognitive outcomes in older adults, such as mild cognitive impairment and dementia, and to identify potential mediators of the association between personality and cognitive trajectories.
Vikram Patel and other global mental health leaders call for a special session of the UN General Assembly to discuss and debate action needed on mental, neurological, and substance use disorders, which have been left off the international NCDs agenda.
