Sex, sleep duration and the association of cognition: Findings from the china health and retirement longitudinal study

Background: We aimed to examine the association between sleep duration and cognitive impairment among elderly Chinese people. Methods: generalized linear modeling was used to analyze the baseline data for adults aged 65 years and over (n = 4785) selected from the 2011 China Health and Retirement Longitudinal Study (CHARLS). The two aspects of cognitive impairment assessed in the study were mental status and memory. Sex-stratified logistic regression models were conducted to identify the effect of sleep duration in the different gender groups. Results: of all the participants, 49.8% were females and 32.5% aged 75 years and over. Of the participants, 59.7% had short sleep duration (\u3c7 h/day), and 9.0% of them had long sleep duration (\u3e8 h/day). Compared to normal sleep duration, long sleep duration was associated with lower mental status scores (β = −0.43, p = 0.001) and lower memory scores (β = −0.26, p = 0.006). Long sleep duration was associated with lower mental status in both men (β = −0.37, p = 0.033) and women (β = −0.46, p = 0.025), however, only in men was long sleep duration found to be associated with low memory scores (β = −0.26, p = 0.047). Conclusions: Our study showed that long sleep duration was significantly associated with poorer mental status and memory scores in elderly Chinese people. Paying greater attention to the effects of sleep patterns on the risk of cognitive decline may yield practical implications for dementia prevention and health promotion, especially among older women with lower educational attain-ment, living in rural areas, and those who have long sleep duration

Climate Change is an Emerging Threat to Perinatal Mental Health

Objective: In this discussion, we build the case for why climate change is an emerging threat to perinatal mental health. Method: A search of current literature on perinatal and maternal mental health and extreme weather events was conducted in PubMed/MEDLINE and Web of Science databases. Only articles focusing on maternal mental health were included in this narrative review. Results: The perinatal period represents a potentially challenging timeframe for women for several reasons. Necessary role adjustments (reprioritization), changes in one’s ability to access pre-birth levels (and types) of social support, fluctuating hormones, changes in body shape, and possible complications during pregnancy, childbirth, or postpartum are just a few of the factors that can impact perinatal mental health. Trauma is also a risk factor for negative mood symptoms and can be experienced as the result of many different types of events, including exposure to extreme weather/natural disasters. Conclusion: While the concepts of “eco-anxiety,” “climate despair,” and “climate anxiety” have garnered attention in the mainstream media, there is little to no discussion of how the climate crisis impacts maternal mental health. This is an important omission as the mother’s mental health impacts the family unit as a whole

THE PREVALENCE OF MATERNAL SMOKING INTENSITY STATUS IN EARLY AND LATE PREGNANCY AND ITS ASSOCIATION WITH EARLY MORBIDITY IN SINGLETON TERM BIRTHS IN THE UNITED STATES, 2016

Relatively little is known about how maternal cigarette smoking influences the health of infants delivered at term. This study was based on the 2016 United States Natality File of live births (N= 3,956,112). The first aim was to examine the prevalence and patterns of smoking in the three months before and during pregnancy and the distribution of smoking intensity in early (1st and 2nd trimester) and late (3rd trimester) pregnancy across race/ethnicity, age, and educational attainment of mothers with all births and with singleton term births (37-41 completed weeks gestation) in the United States in 2016. The second aim was to compare the odds of low birthweight (LBW), low 5-minute Apgar score, and neonatal intensive care unit (NICU) transfer/admission in term singletons with changing maternal smoking status in early and late pregnancy indicating a potential prenatal exposure effect. The third aim was to test and identify the role of low birthweight, as a potential mediator, in the association with maternal smoking status and NICU transfer/admission of a newborn delivered at term. The prevalence of smoking in the three months before pregnancy was 9.42% among all mothers and 9.20% among mothers of term singletons, and high intensity smoking was the highest in the first trimester among non-Hispanic White women, 20-24 years of age, and less educated women for all births and for singleton term births. High intensity smoking in early and late pregnancy was associated with a greater risk of LBW (aOR 3.33; 95% CI: 3.23, 3.44), low 5-min Apgar score (aOR 1.46; 95% CI: 0.88, 2.44), and NICU transfer/admission (aOR 1.62; 95% CI: 1.58, 1.67) in term neonates. The odds ratios of the natural direct and natural indirect effects of NICU transfer/admission were aOR 1.52 (95% CI: 1.47, 1.57) vs. aOR 1.07 (95% CI: 1.07, 1.09) and the proportion mediated through LBW (18.3%) indicated partial mediation. This study has important implications for clinical practice, public health policy and research, and it is particularly timely because of an information gap on the health of infants delivered at term with LBW to mothers who continue smoking at high intensity during pregnancy

A gestational vulnerability window for smoking exposure and the increased risk of preterm birth: how timing and intensity of maternal smoking matter

Abstract Background Reducing the incidence of preterm birth is a national priority. Maternal cigarette smoking is strongly and consistently associated with preterm birth. The objective of this study was to examine prenatal exposure based on combined measures of timing (by trimester) and intensity level (the number of cigarettes smoked per day) of maternal smoking to identify a pregnancy period with the highest risk of preterm birth. Methods A sample of 2,485,743 singleton births was drawn from the 2010 National Center of Health Statistics (NCHS) linked birth/infant death file of US residents in 33 states that implemented the revised 2003 birth certificate. Nine mutually exclusive smoking status categories were created to assess prenatal exposure across pregnancy in association with preterm birth. Gestational age was based on the obstetric estimate. Multiple logistic regression analyses were conducted to compare the odds of preterm birth among women who smoked at different intensity levels in the second or third trimester with those who smoked only in the first trimester. Results Overall, 7.95% of women had a preterm birth; 8.90% of low intensity (less than a pack/day) smokers in the first trimester only, 12.99% of low and 15.38% of high intensity (pack a day or more) smokers in the first two trimesters, and 10.56% of low and 11.35% of high intensity smokers in all three trimesters delivered preterm. First and second trimester high (aOR 1.85, 95% CI: 1.66, 2.06) and low intensity smokers (aOR 1.51, 95% CI: 1.41, 1.61) had higher odds of preterm birth compared to those who smoked less than a pack a day only in the first trimester, but the odds did not increase for all three trimester smokers relative to the first and second trimester smokers. In sensitivity analysis, adjustment for exposure misclassification error corrected data and testing for effect modification by maternal race/ethnicity found no significant interaction. Conclusions This study documented a biologically plausible vulnerability window for smoking exposure and the increased risk of preterm birth. For women who do not modify their smoking behavior preconception, preterm birth risk of smoking remains low until late in the first trimester

Interaction Effects of Maternal Sexually Transmitted Infections with Prenatal Care Utilization Status on Preterm Birth and Low Birthweight: U.S. National Data

This case-control study aimed to test interaction between the most common sexually transmitted infections (STIs) (i.e., chlamydia, gonorrhea, and syphilis) and prenatal care (PNC) utilization status on preterm birth (PTB) (<37 weeks gestation) and low birthweight (LBW) (<2500 g). We used data of participants with singleton live births (N = 3,418,028) from the 2019 United States National Vital Statistics System. There were 280,206 participants in the PTB group and 3,137,822 in the control group, and 221,260 participants in the LBW group and 3,196,768 in the control group. Nearly 1.9% of the participants had chlamydia, 0.3% had gonorrhea, and 0.2% had syphilis. Interaction effects of STIs with PNC utilization status on the risk of PTB and LBW were tested on the multiplicative and additive scales. Using measures of the relative excess risk of interaction (RERI), the attributable proportion of interaction (AP), and the synergy index (S), we observed the highest significant synergistic interaction between syphilis and inadequate PNC utilization increasing the risk of PTB (RERI 2.12, AP 38%, and SI 1.88), and between gonorrhea and inadequate PNC utilization increasing the risk of LBW (RERI 1.03, AP 28%, and SI 1.64). Findings from this study help improve our understanding of disease etiology and inform prevention planning

To Guide or to Self-Guide?: Predictors of Preferring a Guided Introduction to Digital Resources That Promote Postpartum Mental Health

The first postpartum year presents threats to the mental health of birthing parents and obstacles to accessing care. Digital mental health interventions (DMHIs) hold potential to increase postpartum mental healthcare access. However, DMHIs tend to promote limited engagement particularly when they are self-guided (when they do not involve contact with a provider). Yet, given that provider support is a limited resource, a balance must be struck between accessibility and intervention intensity (i.e., involving more human contact). Towards achieving this balance, this analysis seeks to identify characteristics that are associated with a reported preference for a human-guided introduction to digital resources aimed at promoting postpartum mental health. In a sample of largely White, non-Latinx, employed, married, and graduate school-educated individuals, multivariate logistic regression revealed that age (p = 0.0095), level of postpartum functioning (p = 0.0057), depression symptoms (p = 0.0099), and anxiety symptoms (p = 0.03) were associated with guide preference. Specifically, more anxious or lower-postpartum-functioning individuals were more likely to report preferring a guide while older or more depressed individuals were less likely to report preferring a guide. These findings can inform clinical recommendations surrounding who is most likely to engage with, and thus benefit from, exclusively self-guided DMHIs during the postpartum period

Job-related stress and tobacco smoking: A systematic review

Job-related stress may affect smoking initiation, progression, and intensity, therefore, it is important to have a better understanding of these associations to design targeted and effective workplace cessation programs. In this study, we aimed to synthesize existing literature concerning the relationship between job-related stress and tobacco use among adult workers (18 years and older). We searched articles indexed in six major databases (Scopus, PubMed, Embase, Web of Science, EBSCO, and Ovid) between 1997 and March 2020. We included cross-sectional and cohort studies published in English that examined self-reported smoking status or change in smoking status as exposure variables, and job-related status as the outcome variable consistent with the Demand Control Support and Effort-Reward Imbalance models. We searched the databases using combinations of keywords including “occupational stress,” or “job stress” or “work stress” or “job strain” and “smoking” or “tobacco use” or “tobacco consumption” or “cigarettes.” Of 906 identified articles, 19 (n = 240,787 participants) were included in this review. Findings showed no clear association between job-related stress and smoking status (smoking vs nonsmoking) and smoking cessation. However, the findings suggest an association between job-related stress and changing smoking habits, toward heavier smoking. Our findings indicate that job-related stress may lead to increased smoking intensity
