Association of Nighttime Sleep Duration with Depressive Symptoms and Its Interaction with Regular Physical Activity among Chinese Adolescent Girls.

ABSTRACT: Depression has become a major mental health concern among adolescents globally, and the relationship between depressive symptoms and nighttime sleep duration among adolescent girls remains unclear. This study aimed to examine the association between nighttime sleep duration and depressive symptoms among Chinese adolescent girls. This cross-sectional study, conducted in 2018, included 4952 girls aged 10-19 years from the eastern, central, and western regions of China. Depressive symptoms were assessed by the Patient Health Questionnaire-9, and categorized into depressive symptoms and non-depressive symptoms. Logistic regression models were used to estimate the odds ratios (ORs) of depressive symptoms. After adjustment for covariates, adolescent girls with a nighttime sleep duration of <7 h/night (OR = 2.28, 95% CI: 1.76-2.95) and 7 h/night (OR = 1.82, 95% CI: 1.48-2.24) were associated with increased risk of depressive symptoms, compared to those with a sleep duration of 8 h/night. An interaction between nighttime sleep duration and regular physical activity on the risk of depressive symptoms was observed (p for interaction = 0.036). Among both girls with and without regular physical activity, a sleep duration of <7 h/night was associated with increased odds of depressive symptoms, and the magnitude of the ORs among girls with regular physical activity was lower than those without regular physical activity. This study found a significant association of short nighttime sleep duration with increased risk of depressive symptoms, and demonstrates the importance of maintaining adequate nighttime sleep duration and ensuring regular physical activity in improving depressive symptoms among adolescent girls.

Project description:BackgroundIn sub-Saharan Africa (SSA), adolescent girls and young women are three times more likely than boys to have depressive disorders. Understanding adolescents' unique and common vulnerabilities and protective factors is essential for the development of appropriate interventions and programming focused on child and adolescent mental health. This paper examines the prevalence and predictors of depressive symptoms among high school adolescent girls in southern Uganda.MethodsBaseline data from a longitudinal cluster randomized study involving 1260 adolescent girls (14-17 years), recruited from 47 secondary schools were utilized. Depressive symptoms were estimated using the 21-item Beck's Depression Inventory. Hierarchical linear regression modelling was utilized to estimate key predictors of depressive symptoms among adolescent girls.ResultsOf the total sample, 16.35% (n = 206) reported severe depressive symptoms and almost one in every three adolescent girls interviewed (29.68%, n = 374) reported moderate symptoms. These symptoms were more prevalent among older adolescents (16 years and above). In addition, family relationships, social support, as well as measures of psychological wellbeing (self-concept and self-esteem) were all associated with lower levels of depressive symptoms. Hopelessness was associated with higher levels of depressive symptoms among adolescent girls.ConclusionFindings from this study indicate a high prevalence of depressive symptoms, especially among older adolescent girls. In addition, family support factors and adolescents' psychological wellbeing were associated with low levels of depressive symptoms -pointing to the need to strengthen family functioning and adolescent's psychological wellbeing to mitigate risks. Taken together, findings support increasing calls for early screening and detection of depressive symptoms to facilitate timely referral to care and treatment. Findings may also inform the development and incorporation of gender-specific mental health components in programming targeting adolescent girls, in low-resource communities in SSA.Trial registrationThis trial was prospectively registered with ClinicalTrials.gov (registration number: NCT03307226 ) on 11 October 2017.

Project description:BackgroundInduced abortion among adolescent girls is a global public health issue and a serious challenge in China, but still remains under-examined. We aimed to examine the overall trend and characteristics of induced abortions among Chinese adolescent girls and to investigate the factors associated with induced abortion.Study designBased on the 2017 China Fertility Survey, this study examined the trend and characteristics of induced abortions among adolescent girls with statistical analysis and multiple indicators of descriptive statistics from period and cohort perspectives, including induced abortion proportion and rate, age-specific cumulative proportion, and age-specific cumulative number of induced abortions in adolescent girls.ResultsBetween 1996 and 2016, the proportion and rate of adolescent induced abortions first increased and then decreased, and the mean age at the time of induced abortions among adolescent girls declined. The cumulative proportion of women who had experienced induced abortion at the age of 15-19 in a cohort is less than 2.5% but shows an upward trend. Over 70% of all adolescent induced abortions are premarital. The proportion of women with unintended pregnancy experiences increased and is higher among rural, less educated, and ethnic minority women. Similarly, the prevalence of induced abortion is higher among adolescent girls who live in rural areas, are less educated, and come from ethnic minorities. The cumulative number of induced abortions and premarital abortions increased with later cohorts.ConclusionsThis study shows an upward trend in adolescent-induced abortion and a decline in the age at the time of the induced abortion. Women in later birth cohort have a higher proportion of having experienced adolescent induced abortion. Adolescent girls who live in rural areas, who are less educated, or who are from ethnic minorities, are more likely to undergo induced abortions at the age of 15-19. More appropriate educational efforts and interventions are urgently needed to reduce the incidence of adolescent induced abortions.
