Why Women Sit: Determinants of Leisure Sitting Time for Working Women

BackgroundSedentary behavior is associated with negative health consequences independent of physical activity levels. Evidence suggests the work environment promotes sedentary behavior regardless of sector, and that employees with occupations requiring longer sitting times differ only marginally in leisure sitting time from those with more active occupations. Because physical activity opportunities may be limited across many work settings, leisure sedentary time may be more easily replaced with physical activity. Understanding correlates of leisure sedentary behaviors could inform interventions, specifically for women who are among the least active in America.MethodsFemale employees at two universities completed online surveys (n = 156; mean age, 45.12 [SD = 12.5]; mean BMI, 26.7 kg/m² [SD = 5.9]; mean work hours/week, 43.7 [SD = 9.4]). Bivariate correlations and two hierarchical regression analyses were conducted to examine personal and behavioral correlates of weekday and weekend leisure sitting time.FindingsFinal regression models revealed that greater weekday leisure sitting time (R² = 0.307) was related with being older (p = .006), having fewer children (p = .001), self-reporting poorer health (p = .006), and greater weekend sitting time (p < .001). Greater weekend leisure sitting time (R² = 0.261) was related with greater work-related sitting time (p = .020) and greater weekday leisure sitting time (p < .001). Physical activity was not related with weekday or weekend leisure sitting time.ConclusionsThe most prominent correlates of leisure sitting time were other types of sedentary behaviors. This suggests that sedentary time in one segment of life predicts time spent sitting in other areas of life. Future interventions should target decreasing sedentary behaviors during leisure time specifically, in addition to increasing physical activity behavior.     

Associations of overall sitting time and sitting time in different contexts with depression,anxiety, and stress symptoms

Spending a lot of time sitting has been linked to more depressive symptoms and spending a lot of time engaged in screen-based sitting has been linked to greater likelihood of having mental disorders and poorer psychological distress. The purpose of this study was to examine whether overall sitting time and time spent sitting in different contexts was associated with depression, anxiety, or stress symptoms. Sitting time (time spent sitting on typical work- and non-work days while engaged in leisure activities, working, using a computer, watching television, and in transport) and symptom severity of depression, anxiety, and stress were self-reported in a cross-sectional online survey in 2012 by Australian adults (N = 1,104, 55% female, M age = 58 years). Associations were examined using negative binomial regression analyses accounting for the covariates of physical activity, sex, age, income, education, and presence of chronic conditions. Overall sitting time was significantly associated with more severe depression (b = 0.01, 95% CI = 0.00 to 0.02) and anxiety (b = 0.03, 95% CI = 0.02 to 0.04) but not stress (b = 0.01, 95% CI = −0.00 to 0.02) symptoms. Time spent sitting while at a computer was associated with more severe depression (b = 0.04, 95% CI = 0.01 to 0.07) and anxiety (b = 0.03, 95% CI = 0.00 to 0.06) symptoms, and time spent sitting while in transport was associated with more severe anxiety (b = 0.09, 95% CI = 0.05 to 0.13) and stress (b = 0.05, 95% CI = 0.02 to 0.08) symptoms. Limiting overall sitting time and time spent sitting while at a computer or in transport could be potential strategies to improve mental health.     

The role of physical activity enjoyment on the acute mood experience of exercise among smokers with elevated depressive symptoms

ProblemDepressive symptoms are consistently shown to be related to poor smoking cessation outcomes. Aerobic exercise is a potential treatment augmentation that, given its antidepressant and mood enhancing effect, may bolster cessation outcomes for smokers with elevated depressive symptoms. Lower enjoyment of physical activity may inhibit the acute mood enhancing effects of aerobic exercise. The current study investigated the associations between depressive symptoms, physical activity enjoyment and the acute mood experience from exercise among low-active smokers with elevated depressive symptoms.MethodDaily smokers with elevated depressive symptoms (N = 159; M_age = 45.1, SD = 10.79; 69.8% female) were recruited for a randomized controlled exercise-based smoking cessation trial. Participants self-reported levels of depressive symptoms, physical activity enjoyment, and rated their mood experience (assessed as “mood” and “anxiety”) before and after a standardized aerobic exercise test.ResultsHierarchical regression analysis revealed that depressive symptom severity accounted for significant unique variance in physical activity enjoyment (R² = 0.041, t = −2.61, p = 0.010), beyond the non-significant effects of gender and level of tobacco dependence. Additionally, physical activity enjoyment was a significant mediator of the association between depressive symptom severity and acute mood experience (“mood” and “anxiety”) following the exercise test.ConclusionsPhysical activity enjoyment may explain, at least in part, how depressive symptom severity is linked to the acute mood experience following a bout of activity. Interventions that target increasing physical activity enjoyment may ultimately assist in enhancing the mood experience from exercise, and therefore improve smoking cessation likelihood, especially for smokers with elevated depressive symptoms.     

Soft Drink Consumption and Mental Health in Adolescents: A Longitudinal Examination

PurposePrevious studies showed associations between soft drink consumption and mental health problems in adolescents, but the direction of these effects is unknown. This study examines the hypotheses that soft drink consumption predicts aggression and depressive symptoms over time and that these mental health problems predict soft drink consumption.MethodsInterviews were conducted with 5,147 children and their caregivers from three sites at child ages 11, 13, and 16. At each time point, youth reported on their frequency of consuming soft drinks, aggressive behavior, and depressive symptoms. An autoregressive cross-lagged path model tested reciprocal relationships between soft drink consumption, aggressive behavior, and depressive symptoms over time.ResultsMore frequent consumption of soft drinks was associated with more aggressive behavior at each time point and depressive symptoms at ages 11 and 13 (r = .04 to .18, p ≤ .002). After adjusting for covariates and stability of each behavior over time, soft drink consumption at ages 11 and 13 predicted more aggressive behavior at the next time point (β = .08 and .06, p < .001). Aggressive behavior at age 13 also predicted more soft drink consumption at age 16 (β = .06, p = .002). Soft drink consumption at age 13 predicted fewer depressive symptoms (β = ?.04, p = .007), but depressive symptoms did not predict soft drink consumption.ConclusionsMore frequent consumption of soft drinks may contribute to aggressive behavior in adolescents over time; there is some support for reciprocal relationships. There is no evidence for soft drink consumption contributing to adolescents' depression. Future research should examine longitudinal effects over shorter intervals.     

Physical activity characteristics and depressive symptoms in older Latino adults

BackgroundPhysical activity (PA) has been consistently associated with fewer depressive symptoms in observational and intervention studies. Emphasis on leisure-time PA, reliance on self report measures of PA, and lack of inclusion of racial/ethnic minority populations have contributed to uncertainty regarding the minimal and optimal dose (minutes/day), intensity (i.e., light, moderate, or vigorous), bout duration (i.e., incidental vs. 10-min bouts), and domain (i.e., leisure-time, occupational, and household) of PA for reducing and preventing depressive symptoms across diverse populations.PurposeTo investigate the relationship between PA characteristics (i.e., dose, intensity, bout duration, and domain) and depressive symptoms in older Latinos using both objective and subjective measures of PA.MethodsOlder Latinos (n = 174) completed questionnaires and wore accelerometers for seven days. Accelerometer output provided daily minutes of sedentary, light, and moderate-vigorous PA (MVPA) overall and in 10-min bouts. The Community Healthy Activity Model Program for Seniors (CHAMPS) questionnaire provided daily minutes of leisure-time PA, household PA, and sedentary activities. Hierarchical linear regression analysis was used to predict Center for Epidemiological Studies Depression Scale (CES-D) score.ResultsAfter controlling for established correlates of depressive symptoms (i.e., demographics, acculturation, and health characteristics), MVPA in ≥10-min bouts independently predicted fewer depressive symptoms (β = ?.231, ΔR2 = .052, p ≤ .01) and household PA greater depressive symptoms (β = .263, ΔR2 = .056, p ≤ .001).ConclusionsResults suggest that PA intensity, bout duration, and domain influence the strength and direction of the relationship between PA and depressive symptoms in older Latino adults.     

Is Depression Associated with Contraceptive Motivations,Intentions, and Use Among a Sample of Low-Income Latinas?

BackgroundLatinas in the United States experience high rates of unintended pregnancy and low rates of contraception use, yet reasons are not completely understood. Depression is common among pregnant and nonpregnant Latinas; its influence on contraceptive motivations, intentions, and use is understudied.ObjectivesWe sought to 1) describe Latinas' contraceptive motivations, intentions, and use; 2) use structural equation modeling to test associations between depression and contraceptive self-efficacy/motivations/intentions/use; and 3) determine whether associations differ by pregnancy status.MethodsThis cross-sectional study included Latinas ages 15 to 45 recruited from an urban Federally Qualified Health Center in Baltimore, Maryland. Structured surveys were used to collect data regarding depressive symptoms measured using the PHQ-9. All other constructs were measured with previously validated questions. Constructs included contraceptive self-efficacy, positive and negative contraceptive motivations (perceived advantages and disadvantages of using contraception), contraceptive intentions to begin or continue contraception use, and contraceptive methods currently used.ResultsAmong pregnant Latinas, depression was associated with negative motivations (β = 0.16; p < .05), negative motivations were associated with intentions (β = ?0.22; p < .01), and contraceptive self-efficacy was associated with intentions (β = 0.43; p < .001). Among nonpregnant Latinas, contraceptive self-efficacy was associated with intentions (β = 0.78; p < .001) and intentions were associated with use (β = 0.40; p < .05).ConclusionsAmong pregnant Latinas, negative motivations intervene in the association between depression and contraceptive intentions. For nonpregnant Latinas, intentions intervene in the association between self-efficacy and contraceptive use. This study underscores the importance of depression screening during pregnancy and encourages practitioners to target contraceptive motivations to improve contraceptive use.     

Associations between sitting time and health-related quality of life among older men

Statement of problemWhile physical activity is positively associated with more optimal health-related quality of life (HRQoL), less is known about the associations between sedentary behavior and HRQoL. The purpose of this study was to determine associations of total sitting time with HRQoL among older men.MethodsOlder-aged men 55 years of age and older (N = 375) completed a mailed survey that assessed demographic and health information, weekday and weekend sitting time, and HRQoL (RAND-12).ResultsParticipants averaged 9.3 h (SD = 7) of sitting time for weekday and 8.3 h (SD = 5.2) of sitting time for weekend. For weekday, all three adjusted HRQoL models (i.e., physical, mental, and global health) indicated no significant differences in HRQoL across weekday sitting time quartiles (Q) (all p's > .36). For weekend, all three adjusted models indicated significant associations. Differences were observed for Q1 and Q4 (the lowest and highest quartiles, respectively) on physical (M_diff = 2.3, p = 0.05), mental (M_diff = 2.9, p < 0.05), and global health (M_diff = 2.2, p < 0.05). Overall, older men engaged in significantly more total sitting minutes per day on the weekday compared to the weekend (511.6 v. 556.9, p > 0.01).ConclusionOlder men spend the majority of their waking hours engaged in sedentary behaviors. Weekend sitting time was associated with HRQoL when comparing the lowest and highest quartiles.     

Objectively measured and self-reported leisure-time sedentary behavior and academic performance in youth: The UP&DOWN Study

ObjectiveTo examine the associations of (i) objectively measured and self-reported sedentary behavior during leisure time with academic performance and (ii) patterns of sedentary behavior with academic performance.MethodsThis study was conducted with 1146 youth aged 12.5 ± 2.5 years in Spain during 2011–2012. Leisure-time sedentary behavior during out-of-school hours was assessed by accelerometry and self-report. Academic performance was assessed through school grades.ResultsObjectively measured sedentary leisure-time was not significantly associated with academic performance. Time spent in Internet surfing, listening to music, and sitting without doing anything were negatively associated with all academic performance indicators (β ranging from − 0.066 to − 0.144; all p < 0.05). However, time spent in doing homework/study without computer and reading for fun were positively associated (β ranging from 0.058 to 0.154; all p < 0.05). Five major sedentary patterns were identified. The “high social-low TV/video” and the “low studying-high TV/video” patterns were negatively associated with all academic indicators (β ranging from − 0.085 to − 0.148; all p < 0.05). The “educational” pattern was positively associated with all academic indicators (β ranging from 0.063 to 0.105; all p < 0.05).ConclusionsSpecific domains of self-reported sedentary behavior during leisure-time, but not objectively measured sedentary leisure time, may influence academic performance.     

The effects of 60 minutes of supervised weekly walking (in a single vs. 3–5 session format) on depressive symptoms among older women: Findings from a pilot randomized trial

ObjectiveTo investigate the effects of training frequency on psychological benefits resulting from a walking program among older women with subsyndromal depression.MethodsAll participants were randomly assigned to a 4-week-long self-paced walking program including one (G₁) or three to five (G_3–5) weekly training sessions. They completed the Geriatric Depression Scale (GDS) as a measure of depressive symptoms during the intervention and one month later.ResultsUsing statistics for small-n designs, it appeared that, at the end of the program, a significantly greater proportion of women in G_3–5 reported GDS values below the cutoff score of 10 (i.e., indicative of the absence of any depressive symptoms) compared to women in G₁ (5 of 6 vs. 1 of 6; Φ² = 0.48; p < .05). The GDS scores after treatment were significantly lower than baseline scores in both groups (Z = 2.20; p < .03, and Z = 1.99; p < .05 respectively), but the mean decrease of depressive symptoms was significantly larger in G_3-5 (48.9%) than in G₁ (22.7%).ConclusionBreaking 60 min of weekly walking into shorter periods on 3–5 days a week appears to be more effective to alleviate depressive symptoms in older women with subsyndromal depression.     

The association between past and current physical activity and depressive symptoms in young adults: a 10-year prospective study

PurposeThe objectives of this study were to assess (1) the longitudinal associations of past moderate-to-vigorous physical activity (MVPA) and involvement in team sports during secondary school with depressive symptoms in early adulthood, and (2) the cross-sectional associations of current MVPA and involvement in team sports with depressive symptoms during young adulthood.MethodsData were drawn from the Nicotine Dependence in Teens study, which is an ongoing prospective cohort study of 1293 adolescents aged 12–13 years at baseline (52% female). Data analyses involved latent growth curve modeling and multiple hierarchical linear regression models.ResultsCurrent MVPA (β = ?0.12), but not past MVPA, participation was significantly negatively related to depressive symptoms during young adulthood (P < .05). Both current and past involvement in team sports were significantly negatively related to depressive symptoms (β ≥ ?0.09; P < .05); however, these associations were no longer significant (P = .08) when covariates were controlled for.ConclusionsFindings provide insight about the unique associations between the timing and type of physical activity and depressive symptoms, suggesting that physical activity within team sport contexts should be encouraged so that young adults may experience less depressive symptoms.     

Associations between physical activity,television viewing and postnatal depressive symptoms amongst healthy primiparous mothers

BackgroundPostnatal depression is a serious illness in new mothers. In the general population, physical activity (PA) has been found to reduce the risk of depression, whilst sedentary behaviour (SB; in particular television viewing) has been linked to higher levels of depressive symptoms, yet little is known regarding associations between PA, SB and postnatal depression. This study aimed to investigate associations between PA, television viewing and postnatal depressive symptoms in healthy primiparous mothers..MethodsCross-sectional survey data were provided by 406 first-time mothers (approximately 3-months postpartum) enrolled in the Melbourne InFANT Extend trial (2012/2013). Women self-reported PA (time spent walking for leisure and transport, and other moderate and vigorous PA), television viewing, and depressive symptoms (CES-D 10). Random intercept linear models examined associations between PA, television viewing and depressive symptoms.ResultsIn crude models total PA was inversely associated with risk of postnatal depressive symptoms (B = −0.122; 95% CI = −0.24, -0.01). In models adjusted for key sociodemographic and behavioural covariates the association did not remain statistically significant. No other associations between PA, television viewing and postnatal depressive symptoms were evident..ConclusionsPostnatal depressive symptoms may not be related to PA and television viewing in the same way that these behaviours predict depressive symptoms in the general population. Further investigation of the specific domains of PA, as well as different types/contexts of SB and their respective associations with postnatal depressive symptoms is warranted in order to better inform development of targeted interventions aimed at enhancing postnatal mental health..     

Living Alone and Depressive Symptoms among Older Adults in the COVID-19 Pandemic: Role of Non–Face-to-Face Social Interactions

ObjectiveThis study examined the association of living alone with changes in depressive symptom status and the moderating effect of non–face-to-face social interactions among older adults during the coronavirus disease (COVID-19) pandemic.DesignA longitudinal study.Setting and ParticipantsThis study recruited individuals aged ≥ 65 years without long-term care in one semi-urban city in Japan, who completed mailed questionnaires in March (baseline) and October 2020 (follow-up).MethodsBased on depressive symptoms assessed by the Two-Question Screening at baseline and follow-up, participants were classified as: “non-case,” “onset,” “remission,” and “persistence.” Non–face-to-face social interactions during the pandemic, including phone calls or emails with separated families or friends, were dichotomized as “less than weekly interactions” and “weekly interactions.” A multinomial logistic regression analysis was conducted to examine the association of living arrangement (living alone or together) with changes in depressive symptoms status.ResultsData of 1001 participants were analyzed (mean age = 79.9 years). Of them, 13.8% lived alone. Overall, 40.6% participants were grouped as “non-case,” 11.7% as “onset,” 11.0% as “remission,” and 27.1% as “persistence.” Living alone was significantly associated with depressive symptom onset (odds ratio: 1.92; 95% CI: 1.03–3.56; P = .039), and a negative interaction (protective effect) was found between living alone and weekly non–face-to-face social interactions for depressive symptom onset.Conclusion and ImplicationsDuring the pandemic, older adults living alone had a higher depressive symptom risk, but non–face-to-face social interactions may have buffered this risk. Our findings suggest the importance of supporting older adults living alone in times of social restrictions such as the pandemic, and furthermore, maintaining social connections, including non–face-to-face relationships, is necessary to protect their mental health.     

Stress,Lifestyle, and Quality of Life in Midlife and Older Australian Women: Results From the Stress and the Health of Women Study

BackgroundChronic psychological stress may pose a serious threat to health, although the mechanisms are not fully understood. This study examines the impact of stress on modifiable lifestyle factors, depressive symptoms, health-related quality of life (HRQOL) and chronic illness in older Australian women.MethodsCross-sectional data were collected from a random sample of 181 older adults aged 60 to 70 years from rural and urban areas of South-East Queensland, Australia. We used structural equation modelling to examine associations between stress, modifiable lifestyle factors, HRQOL, and chronic illness.FindingsParameter estimates show that older women who reported life stressors where they felt helpless and feared for their life (high-magnitude stressors) also reported higher body mass index (p = .03) and more chronic illness (p < .01). In contrast, duration of exposure to life stressors was associated with higher depressive symptom scores (Center for Epidemiologic Studies Depression Scale; p = .02) and sleep disturbance scores (p < .01).ConclusionsOur findings support the link between traumatic personal histories (exposure to high-magnitude stressors) and unhealthy lifestyle factors. Findings highlight the need for more research on how stress reduction, a healthy lifestyle, and positive coping strategies can be used to reduce the effects of high-magnitude stress on HRQOL and chronic illness.     

Exploring the Impact of Racism on Black Youth: A Multidimensional Examination of Discriminatory Experiences Across Place and Time

PurposeCommunity violence disproportionally impacts Black youth. Experiences of racism and discrimination may create additional challenges for youth recovering from violence exposure. This study used ecological momentary assessment to elucidate how perceptions of racism and social support influence health and safety outcomes among Black youth following violence exposure.MethodsTwenty-five Black youth (14–19 years old, 60% female) who had witnessed violence within the past three months completed a baseline survey that assessed discrimination experiences, social support, post-traumatic stress symptoms (PTS), and perceived safety. Youth completed ecological momentary assessments three times daily for two weeks about the place they were in, people they were with, their current emotional state, and in-the-moment racism perceptions. Multilevel models estimated the relationship between overall and time-varying perceptions of racism and social support, PTS symptoms, and perceived safety.ResultsOverall, 76% of youth reported at least one discrimination experience at baseline. Prior discrimination was associated with higher PTS (B = 1.86, p = .001) and depressive symptoms (B = 0.13, p = .013) at baseline. Youth who reported higher overall perceptions of racism in-the-moment reported higher PTS (B = 0.50, p = .002) and lower perceived safety (B = ?0.53, p = .001). In-the-moment perceptions of racism were associated with lower perceived safety in that place (B = ?0.09, p < .01). Emotional and instrumental support were associated with lower PTS and higher perceived safety (p < .05).DiscussionExperiences of racism and being in discriminatory places impacted youth’s depressive symptoms, PTS symptoms, and perceived safety. Interventions attuned to in-the-moment experiences of racism, and that leverage social support, are needed to support Black youth exposed to violence and discrimination.     

Gender differences in the longitudinal associations of depressive symptoms and leisure-time physical activity with cognitive decline in ≥ 57 year-old Taiwanese

ObjectiveThis study investigates the role of gender in the associations of long-term depressive symptoms and leisure-time physical activity (LTPA) with the risk of cognitive decline in elderly Taiwanese.MethodWe analyzed 3679 subjects (age ≥ 57) in the 2003 and 2007 datasets of the Taiwan Longitudinal Survey on Aging, of which data were collected via face-to-face interviews by trained interviewers. We excluded proxy respondents. Multivariable logistic regression analysis examined the associations of long-term depressive symptoms (increased symptoms: CES-D10 scores from < 10 to ≥ 10; decreased symptoms: from ≥ 10 to < 10) and LTPA (frequency, duration, and intensity) with cognitive decline (a decrease of two or more SPMSQ scores).ResultsWomen had significant higher percentages of cognitive impairment, compared to men, at the baseline (5.9 vs. 1.5%; χ² = 51.24, p < 0.001) and end-point (10.8 vs. 5.2%;χ² = 39.5, p < 0.001). Men with long-term depressive symptoms had 5.28 greater odds of cognitive decline (OR = 5.28, 95%CI = 2.84–9.82, p < 0.001) and men with increased depressive symptoms had 2.09 greater odds (2.09, 1.24–3.51, p = 0.006). No such association was observed in women. Men with consistently high LTPA had 65% (0.35, 0.19–0.65, p = 0.001) and women with increased LTPA had 43% (0.57, 0.34–0.93, p = 0.024) reduction in odds of developing cognitive decline.ConclusionWe found gender differences in the longitudinal association between depressive symptoms and cognitive decline. Long-term LTPA may loosen the association between long-term depressive symptoms and cognitive decline. These findings are useful in the identification of vulnerable elderly in the Taiwanese population and public health interventions should focus on assisting their cognitive aging.     

Associations between sitting time and weight in young adult Australian women

ObjectiveSedentary behaviour may be a contributor to weight gain in today's young adult women, who are gaining weight faster than women in their mothers' generation. The aim was to examine the relationships between sitting time and weight in young women.MethodData were from women born in 1973–1978 who completed surveys in 2000, 2003 and 2006 for the Australian Longitudinal Study on Women's Health. Associations between concurrent changes in sitting-time and weight, and prospective associations between these variables, were examined using ANOVA and linear regressions, stratified by BMI-category in 2000 (n = 5562).ResultsAmong overweight and obese women, percentage weight change from 2000 to 2006 was higher in those whose sitting time increased (> 20%) than in those whose sitting time decreased (> 20%) over the same period (p < 0.05). Conversely, percentage change in sitting time was significantly higher in those who gained weight (> 5%) than in those who lost weight (> 5%) (p < 0.05). There were no prospective associations between (change in) sitting time and weight change, or between (change in) weight and change in sitting time.ConclusionThe results confirm associations between concurrent changes in weight and changes in sitting time in overweight and obese women, but no prospective relationships were found.     

Relationship of perceived job strain and workplace support to antenatal depressive symptoms among pregnant employees in Taiwan

Most Taiwanese women continue to work throughout pregnancy. Few studies have investigated the prevalence of antenatal depressive symptoms in employed women and their relationship with work-related factors. We explored the relations of work-related factors, including perceived job strain and workplace support, to depressive symptoms among pregnant Taiwanese employees. During 2015–2016, we interviewed 153 employees in their third trimester of pregnancy using questionnaires to collect data on demographics, pregnancy status, physical conditions, work-related factors, family function, the Edinburgh Postnatal Depression Scale (EPDS), and health-related quality of life (HRQoL). The prevalence of antenatal depressive symptoms, based on EPDS scores≥13, was 13.7%. Pregnant employees with depressive symptoms had lower Family APGAR scores (p < 0.0001) and lower scores on all scales of the HRQoL (p < 0.05). Controlling for covariates, work-related feelings of stress and distress were associated with increased odds of antenatal depressive symptoms (Odds Ratio [OR] = 4.7, 95% confidence Interval [95% CI] = 1.3–19.9). Feeling tired at work (OR = 9.1, 95% CI = 2.3–47.0) and lack of support from colleagues (OR = 16.7, 95% CI = 2.9–53.1) were significantly associated with antenatal depressive symptoms. Such information will facilitate implementation of supportive workplace climates for pregnant employees by employers, supervisors, and occupational and environmental health nurses, which may help improve the health of pregnant employees.     

Trajectories of Depressive Symptoms Over 2 Years Postpartum Among Overweight or Obese Women

BackgroundAlthough depressive symptoms are common postpartum, few studies have followed women beyond 12 months postpartum to investigate changes in the number and severity of these symptoms over time, especially in overweight and obese women. Using two complementary analytical methods, this study aims to identify trajectories of depressive symptoms over 2 years postpartum among overweight or obese mothers, and assess the demographic, socioeconomic, and health covariates for these trajectories.MethodsUsing longitudinal data from two behavioral intervention studies (Kids and Adults Now!-Defeat Obesity [KAN-DO] and Active Mothers Postpartum (AMP); n = 844), we used latent growth modeling to identify the overall trajectory of depressive symptoms and how it was related to key covariates. Next, we used latent class growth analysis to assess the heterogeneity in the depressive symptom trajectories over time, and thereby, identify subgroups of women with distinct trajectories.FindingsThe overall trajectory of depressive symptoms over 2 years postpartum was relatively stable in our sample. However, the presence of three distinct latent class trajectories (stable-low [82.5%], decreasing symptoms [7.3%], and increasing symptoms [10.2%]), identified based on trajectory shape and mean depressive symptom score, supported heterogeneity in depressive symptom trajectories over time. Lower maternal education was related to a higher symptom score, and poorer subjective health status at baseline predicted inclusion in the increasing symptoms trajectory.ConclusionsIn some overweight or obese mothers, postpartum depressive symptoms do not resolve quickly. Practitioners should be aware of this phenomenon and continue to screen for depression for longer periods of time postpartum.     

Frailty Predicts New and Persistent Depressive Symptoms Among Community-Dwelling Older Adults: Findings From Singapore Longitudinal Aging Study

ObjectiveThis study aimed to examine the cross-sectional and longitudinal relationships between physical frailty at baseline and depressive symptoms at baseline and at follow-up.DesignFour-year prospective study.SettingCommunities in the South East Region of Singapore.ParticipantsWe analyzed data of 1827 older Chinese adults aged 55 and above in the Singapore Longitudinal Aging Study-I.MeasurementsThe frailty phenotype (based on Fried criteria) was determined at baseline, depressive symptoms (Geriatric Depression Scale ≥5) at baseline and follow-ups at 2 and 4 years.ResultsThe mean age of the population was 65.9 (standard deviation 7.26). At baseline, 11.4% (n = 209) had depressive symptoms, 32.4% (n = 591) were prefrail and 2.5% (n = 46) were frail. In cross-sectional analysis of baseline data, the adjusted odds ratios (OR)s and 95% confidence intervals controlling for demographic, comorbidities, and other confounders were 1.69 (1.23–2.33) for prefrailty and 2.36 (1.08–5.15) for frailty, (P for linear trend <.001). In longitudinal data analyses, prospective associations among all participants were: prefrail: OR = 1.86 (1.08–3.20); frail: OR = 3.09 (1.12–8.50); (P for linear trend = .009). Among participants free of depressive symptoms at baseline, similar prospective associations were found: prefrail OR = 2.26 (1.12–4.57); frail: OR = 3.75 (1.07–13.16); (P for linear trend = .009).ConclusionThese data support a significant role of frailty as a predictor of depression in a relatively younger old Chinese population. Further observational and interventional studies should explore short-term dynamic and bidirectional associations and the effects of frailty reversal on depression risk.
