German population norms of the preference to solitude scale and its correlates

AIM

Our first aim was to present norm values for the Preference for Solitude Scale by sex, age, and other sociodemographic groups. Our second aim was to evaluate the correlates of preference for solitude.

METHODS

Data were collected in August/September 2023 from a sample of individuals (N = 5000) living in Germany aged 18 to 74 years (ensuring representativeness in terms of sex, age group and federal state for the German general adult population). The established and valid Preference for Solitude Scale (range 0 to 12, with higher values reflecting a stronger preference for solitude) was used to quantify the preference for solitude. Norm values were provided by sex and age groups. Multiple linear regressions were used to examine the correlates of preference for solitude.

RESULTS

Average preference for solitude score was 7.6 (SD = 3.0; 0 to 12). The average score was 7.3 (SD = 3.0) among males and 7.9 (SD = 2.9) among females. Regressions showed that a stronger preference for solitude was associated with being female (β = .51, p < .001), being older (e.g., being 40 to 49 years compared to 18 to 29 years, β = .85, p < .001), being single (e.g., divorced compared to being single, β = -.78, p < .01), higher level of education (secondary education compared to primary education, β = .43, p < .01), never been a smoker (e.g., daily smoker compared to never smokers, β = -.61, p < .001), absence of alcohol consumption (e.g., drinking once a week compared to never drinking, β = -1.09, p < .001), no sports activity (e.g., 2-4 hours per week compared to no sports activity, β = -.60, p < .001), poorer self-rated health (β = .28, p < .001) and more depressive symptoms (β = .05, p < .001). Sex-stratified regressions yielded similar results.

CONCLUSION

Norm values provided in this study can be used as a benchmark for comparison with other countries and can guide further research dealing with preferences for solitude. We demonstrated the importance of several sociodemographic factors (e.g., marital status), lifestyle-related factors (e.g., sports activity), and health-related factors (e.g., depressive symptoms) for the preference for solitude. Such knowledge about the correlates of preference for solitude may help to characterize them. This is essential to ensure a good balance between social interaction and being alone. This is important because preference for solitude is associated with poor self-rated health and depression, but also with healthy behaviors such as abstaining from smoking and drinking.

Prevalence and correlates of psychological distress among national community-based adult populations in Nauru, Tukelau and Tuvalu

AIMS

The aim of the study was to estimate the prevalence and correlates of psychological distress (PD) in three small Pacific Island countries.

METHOD

National cross-sectional data (pooled sample N = 3,088, 18-69 years) of participants from the STEPS surveys in Nauru (2015/16; N = 1382), Tukelau (2014; N = 554) and Tuvalu (2015; N = 1152) were analysed.

RESULTS

In the pooled sample 30.4% participants had PD (⩾20 scores), 18.1% mild (20-24 scores), 7.8% moderate (25-29 scores) and 4.4% severe (30-50 scores) PD. The prevalence of PD in Nauru was 41.5%, in Tukelau 5.0% and in Tuvalu 22.7%. In the adjusted logistic regression analysis with the pooled sample, younger age (18-39 years), alcohol family problems, heart attack/stroke, current smoking, high salt intake and high sedentary behaviour were positively associated with PD, while male sex and being from Tukelau and Tuvalu were negatively associated with PD.

CONCLUSION

Almost one in three participants reported PD and several associated factors were found that can be targeted in population interventions.

Longitudinal Correlates of Grandparenting with Depressive Symptoms and Poor Sleep Quality Among Middle-Aged and Older Women and Men in South Africa

OBJECTIVES

The study aimed to assess the impact of grandparenting on incident depressive symptoms and incident poor sleep quality among aging women and men in rural South Africa.

METHODS

This longitudinal community study enrolled 3,237 adults (≥40 years) from the "Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI)."

MEASUREMENTS

Grandparenting was assessed by self-report at wave 1, and depressive symptoms and poor sleep quality at waves 1 and 2. Outcomes were incident depressive symptoms and incident poor sleep quality at wave 2. Logistic regression was utilized to estimate the associations between grandparenting and incident depressive symptoms and incident poor sleep quality.

RESULTS

Almost half of the grandfathers (44.6%) and 68.4% of the grandmothers were parenting 7/days/week. In the final adjusted models, among grandmothers, compared to 0 days/week grandparenting, 7 days/week grandparenting reduced the odds of incident depressive symptoms (AOR: 0.71, 95% CI: 0.55 to 0.91) and reduced the odds of incident poor sleep quality (AOR: 0.58, 95% CI: 0.40 to 0.82).

CONCLUSION

Grandparenting significantly reduced poor mental health among grandmothers but not among grandfathers.

CLINICAL IMPLICATIONS

Practitioners may encourage grandparent caregiving, among grandmothers, to reduce poor mental health in South Africa.

Longitudinal Associations Between Food Insecurity and Mental Health in Aging Adults in South Africa

OBJECTIVES

The aim of this study was to assess the longitudinal unidirectional and bidirectional associations between food insecurity and mental health among aging adults in South Africa.

METHODS

The analysis utilized data from the South African 7-year longitudinal Health and Ageing in Africa (HAALSI) study.

RESULTS

The proportion of food insecurity was 20.2% in 2015, 24.1% in 2019 and 18.4% in 2021/2022. Food insecurity was positively associated depressive symptoms, poor life satisfaction, poor sleep quality, PTSD, loneliness, impaired cognition, and current tobacco use. Compared to without food insecurity in all three study waves, having food insecurity in one wave and/or two to three waves was positively associated with incident depressive symptoms, incident poor life satisfaction, incident poor sleep quality, incident PTSD, incident loneliness, incident current tobacco use, and incident current heavy alcohol use. PTSD, impaired cognition, current tobacco use and current heavy alcohol use were positively associated with incident food insecurity.

CONCLUSION

We found that food insecurity was unidirectionally associated with depressive symptoms, poor life satisfaction, poor sleep quality and loneliness, and bidirectionally associated with PTSD, impaired cognition, current tobacco use and current heavy alcohol use.

CLINICAL IMPLICATIONS

Enhanced screening and management of food insecurity may reduce mental ill-health in South Africa.

Stakeholder-Informed Solutions To Address Barriers for Alcohol Screening and Brief Intervention in Thai Hypertension Care

Premature deaths from NCDs disproportionately affect people in low- and middle-income countries. Since alcohol use is one of the most common causes of reversible hypertension, interventions targeting alcohol use may be a feasible and effective low-cost approach to synergistically reduce the prevalence of harmful drinking and high blood pressure. This study sought to identify key factors in successfully implementing alcohol use screening and brief intervention in hypertension care in Thailand. For this purpose, we surveyed participants (NRound 1 = 91, NRound 2 = 27) from three different groups of Thai stakeholders (policy- and decisionmakers, primary healthcare practitioners, and patients diagnosed with hypertension) in a two-round stakeholder elicitation. In round 1, we identified limited resources, lack of clear guidelines for lifestyle intervention, stigmatization, and inconsistent monitoring of patients' alcohol use as important barriers. In round 2, we sought to elicit solutions for the barriers identified in round 1. While stakeholders emphasized the need for adaptability to existing realities in Thai primary healthcare such as a high workload and limited digitization, they favorably evaluated a digital alcohol assessment tool with integrated, tailored advice for brief intervention as a potential scalable solution. Findings suggest that as one possible route to reduce the NCD burden caused by hypertension in Thailand, primary healthcare services may be enhanced by digital tools that support resource-effective, intuitive, and seamless delivery of alcohol screening and brief intervention.

Chronic conditions and incident and persistent depressive symptoms among ageing adults in rural South Africa

The study aimed to assess associations between chronic diseases and incident and persistent depressive symptoms (DSs) in a cohort study of ageing adults in South Africa. Participants in the baseline survey (in 2014/2015) were 5,059 persons (≥40 years) and at follow-up 4,176 (in 2018/2019). DSs were measured with the Center for Epidemiological Studies Depression scale. Logistic regression was used to estimate the associations between chronic conditions and incident and persistent DS. The prevalence of DS at baseline was 15.5%, incident DS (without DS and/or PTSD at baseline) was 25.1% and persistent DS (DS at both baseline and follow-up) was 4.8%. In unadjusted logistic regression analysis, diabetes had higher odds of incident DS. Participants with baseline heart attack/stroke/angina, dyslipidemia, tuberculosis, chronic bronchitis, kidney disease and three or more chronic conditions had a higher probability of persistent DS. In conclusion, of the eight chronic conditions evaluated, only diabetes (in unadjusted analysis) was associated with incident DS, and five chronic conditions (heart attack/stroke/angina, dyslipidaemia, tuberculosis, chronic bronchitis and kidney disease) and three or more chronic conditions were associated with persistent DS.

Associations of history of intimate partner violence with mental ill-health and lifestyle factors in middle-aged and older men and women in South Africa

OBJECTIVES

The aim of this study was to assess the association between history of intimate partner violence (IPV) exposure and mental and lifestyle factors among middle-aged and older men and women in rural South Africa.

METHODS

The analysis utilized data from wave 3 of the longitudinal Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) (n = 3,707, median age 66 years, range 46-118 years). History of IPV was assessed with five questions on physical, sexual, psychological, and economic IPV. Logistic regression was used to assess the association between history of IPV exposure and mental and lifestyle factors.

RESULTS

Among men 7.8% and among women 10.9% reported a history of IPV. In terms of mental health outcomes, in the final adjusted model, among men, exposure to 1 and/or 2-4 types of IPV were associated with depressive symptoms, insomnia symptoms, PTSD, and loneliness, while among women, exposure to 1 and/or 2-4 types of IPV was associated with insomnia symptoms and PTSD. In terms of lifestyle outcomes, in the final adjusted model, among men, 2-4 types of IPV were associated current tobacco use, current heavy alcohol use, inadequate fruit intake, and food insecurity, and among women, 1 and/or 2-4 types of IPV were associated with soft drink intake, and food insecurity.

CONCLUSION

We found that lifetime exposure to IPV was associated with several mental and lifestyle factors in middle-aged and older men and women. Enhanced screening and treatment of IPV may reduce poor mental and health risk behavior among this aging male and female population in South Africa.

Lifestyle factors and incident functional disability among a rural ageing population in South Africa

OBJECTIVE

The study aimed to assess the relationship between lifestyle factors and incident functional disability in South Africa.

METHODS

Longitudinal data (N = 4113) from two consecutive waves in 2014/2015 and 2018/2019 in Agincourt, South Africa, were analysed.

RESULTS

Moderate sedentary behaviour (AOR: 1.84, 95% CI: 1.31-2.58) and being overweight (AOR: 1.61, 95% CI: 1.10-2.36) increased the odds of incident functional disability among men. Moderate and high sedentary behaviour (AOR: 1.83, 95% CI: 1.31, 2.57, and AOR: 1.83, 95% CI: 1.08-3.10) increased the odds, and frequent fruit intake (AOR: 0.41, 95% CI: 0.19-0.91) and moderate physical activity (AOR: 0.47, 95% CI: 0.30-0.75) decreased the odds of incident functional disability among women.

CONCLUSIONS

Sedentary behaviour and being overweight increased odds, and physical activity and frequent fruit intake decreased odds of incident functional disability among ageing men and/or women in South Africa.

Prevalence and correlates of unintentional nonfatal injuries among school-going adolescents in Central America

OBJECTIVES

The aim of this study is to report on the frequency of serious physical injuries (SPI) among adolescents in Central America during the previous decade, 2009-2018.

METHODS

In total, 15,807 school adolescents (14.4 years mean age; SD=1.4) from six Central American countries participated in cross-sectional Global School-based Student Health Surveys in 2009-2018 (ranging from 1,779 students in Honduras in 2012 to 4,374 students in Guatemala in 2015).

RESULTS

The prevalence of SPI was 33.8 % (22.9 % once, 7.4 % 2 or 3 times and 3.6 % 4 or more times), ranging from 31.8 % in Guatemala to 45.0 % in Belize and 45.6 % in Panama. The most frequent causes of SPI included fall (11.4 %, ranging from 6.9 % in Costa Rica to 15.6 % in Panama), and the type of SPI was fracture/dislocation (5.7 %, ranging from 4.3 % in Costa Rica to 6.7 % in Panama). In adjusted Poisson regression, male sex, food insecurity, a history of alcohol intoxication, soft drink consumption, fast food intake, truancy, multiple sexual partners, psychological distress, physical fight, physically attacked, bullied, and suicide attempt were significantly associated with a higher number of injury event counts.

CONCLUSIONS

Overall, about one in three adolescents in Central America had sustained unintentional injuries in the past 12 months and several contributing factors were identified which if addressed could aid injury prevention among adolescents.

Marital status, marital transition and health behaviour and mental health outcomes among middle-aged and older adults in Thailand: A national longitudinal study

OBJECTIVES

The aim of this study was to assess the longitudinal association between marital status, marital transition, mental ill-health, and health risk behaviours among middle-aged and older adults in Thailand.

METHODS

We analyzed prospective cohort data of participants 45 years and older from three consecutive waves in 2015, 2017, and in 2020 (analytic sample, n = 2863) of the Health, Aging and Retirement in Thailand (HART) study. Sociodemographic and health variables were assessed by self-report.

RESULTS

Being single was positively associated with current smoking among men and transitioning to widowed or divorced was associated with incident current smoking among women. Divorced or separated was positively associated with current alcohol use among men and transitioning to marriage was associated with incident alcohol use among women. Being single or widowed was positively associated with underweight and negatively associated with obesity among women. Men who were divorced, single, or widowed had higher odds of having depressive symptoms and among women, transitioning to being widowed or divorced or separated was associated with incident depressive symptoms. Among both men and women, being divorced, single or widowed were positively associated with poor quality of life/happiness, and among men being divorced, single or widowed was positively associated with loneliness, and among women, being single or widowed was positively associated with loneliness. Among men, being single was positively associated with having an emotional or psychiatric disorder.

CONCLUSION

We found among men and/or women that being unmarried was associated with several health risk behaviours and mental-ill health indicators.

Suicidal behaviour among adults in Cabo Verde in 2020

BACKGROUND

The aim of the investigation was to evaluate past 12-month suicidal behaviour (PSB) among adults in Cabo Verde.

METHODS

Data from 4,563 adults (mean age 41.4 years) that participated in the 2020 Cabo Verde STEPS survey were analysed.

RESULTS

Results indicate that the proportion of PSB (attempt 0.6%, plan 1.5% and ideation 3.3%) was 3.7% (2.4% men/5.0% women). In adjusted logistic regression analysis, younger age, female sex, unemployed, widowed or divorced, alcohol family problem, heart attack, angina or stroke, current smokeless tobacco use and low fruit/vegetable intake were associated with PSB.

CONCLUSION

Almost 4% of participants had PSB and several associated factors were identified that can guide public health interventions.

Age-related Disparities in Pan-Cancer Mortality and Causes of Death: Analysis of Surveillance, Epidemiology, and End Results (SEER) Data

Comprehensive analysis of mortality and causes of death (COD) in cancers was of importance to conduct intervention strategies. The current study aimed to investigate the mortality rate and COD among cancers, and to explore the disparities between age. Initially, cancer patients diagnosed between 2010 and 2019 from the surveillance, epidemiology, and end results (SEER) database were extracted. Then, frequencies and percentage of deaths, and mortality rate in different age groups were calculated. Meanwhile, age distribution of different COD across tumor types was illustrated while the standardized mortality ratios (SMR) stratified by age were calculated and visualized. A total of 2,670,403 death records were included and digestive system cancer (688,953 death cases) was the most common primary cancer type. The mortality rate increased by 5.6% annually in total death, 4.0% in cancer-specific death and 10.9% in non-cancer cause. As for cancer-specific death, the age distribution varied among different primary tumor types due to prone age and prognosis of cancer. The top five non-cancer causes in patients older than 50 were cardiovascular and cerebrovascular disease, other causes, COPD and associated conditions, diabetes as well as Alzheimer. The SMRs of these causes were higher among younger patients and gradually dropped in older age groups. Mortality and COD of cancer patients were heterogeneous in age group due to primary tumor types, prone age and prognosis of cancer. Our study conducted that non-cancer COD was a critical part in clinical practice as well as cancer-specific death. Individualized treatment and clinical intervention should be made after fully considering of the risk factor for death in different diagnosis ages and tumor types.

Rural-urban health differences among aging adults in India

Background

The aim of this study was to determine the rural-urban health differences among aging adults in India.

Methods

The national cross-sectional data of 67,489 individuals (≥45 years) in 2017-2018 from 35 states and union territories of India (excluding Sikkim) in 2017-2018 were analysed. Various sociodemographic data, well-being indicators, lifestyle factors and physical conditions were assessed by face-to-face interviews and physical measurement. Univariable and multivariable logistic regression was utilized to assess the predictors between residence status (rural dweller, urban migrant, and urban dweller) and various health indicator outcomes.

Results

Majority (70.4 %) of the participants lived in rural areas, 10.3 % were urban migrants and 19.3 % urban dwellers. In the multivariable logistic regression analysis, urban migrants and urban dwellers had a higher self-rated health status, cognitive functioning, physical inactivity, overweight or obesity and abdominal obesity than rural dwellers, while urban migrants and/or urban dwellers had lower functional disability, insomnia symptoms, current smokeless tobacco use, current smoking, heavy episodic drinking and underweight than rural dwellers. Furthermore, urban migrants and/or urban dwellers had higher odds of diabetes, hypertension, heart disease, cancer, high cholesterol than rural dwellers, while urban migrants and/or urban dwellers had lower odds of persistent headaches, major injury, recurrent fall, physical pain, periodontal disease, vision impairment, and gastrointestinal problems than rural dwellers.

Conclusion

Among 30 health indicators assessed, 16 had an urban migrant and/or urban dweller advantage, 8 had urban migrant and/or urban dweller penalty, and 6 did not differ between rural-urban groups. Public health promotion and health care should address differing health care needs of rural and urban middle-aged and older adults.

Longitudinal associations of loneliness with mental ill-health, physical ill-health, lifestyle factors and mortality in ageing adults in Thailand

OBJECTIVES

The aim of this study was to assess the longitudinal association between loneliness, mental and physical ill-health indicators, lifestyle factors and mortality among middle-aged and older adults in Thailand.

METHODS

We analyzed prospective cohort data of participants 45 years and older from three consecutive waves in 2015 (n = 5616), 2017 (n = 3600), and in 2020 (n = 2863) of the Health, Aging and Retirement in Thailand (HART) study. Loneliness was assessed with a single item. To assess the longitudinal associations between loneliness and health outcomes between 2015 (baseline), 2017 (first follow-up) and 2020 (second follow-up), we conducted Generalized Estimating Equations analysis (GEE).

RESULTS

The proportion of loneliness was 21.6% in 2015, 23.8% in 2017 and 21.3% in 2020. In the adjusted GEE logistic regression model, loneliness was positively associated with mental ill-health (poor self-rated mental health status, poor quality of life/happiness, depressive symptoms, and insomnia symptoms), physical ill-health (poor self-rated physical health status, hypertension, kidney disease, osteoporosis, and ADL disability), and lifestyle factors (physical inactivity, and having underweight). Furthermore, in adjusted Cox proportional hazards regression, loneliness was associated with mortality. In adjusted logistic regression, compared to without loneliness in all three study waves, having loneliness in one wave and/or two to three waves was positively associated with incident mental ill-health (incident poor self-rated mental health status, incident poor quality of life/happiness, incident depressive symptoms, and incident insomnia symptoms), incident physical ill-health (incident poor self-rated physical health status, incident diabetes, incident kidney disease, and incident ADL disability), and incident lifestyle factors (having incident underweight).

CONCLUSION

We found that loneliness was associated with several mental and physical ill-health indicators, lifestyle factors and mortality. Enhanced screening and treatment of loneliness may reduce mental and physical ill-health indicators in Thailand.

Impact of Somatic Conditions and Lifestyle Behaviours on Depressive Symptoms and Low Life Satisfaction among Middle-Aged and Older Adult Men in South Africa

Objective

The purpose of this study was to assess the association between somatic disorders, lifestyle factors, incident and persistent depressive symptoms, and low life satisfaction in a longitudinal study in South Africa.

Methods

We analyzed longitudinal data from two consecutive waves, 2346 men aged 40 years or older in 2014/2015 in wave 1 and 1864 men of wave 1 in 2018/2019 in wave 2 of the "Health and Ageing in Africa: A Longitudinal Study of an International Network for the Demographic Evaluation of Populations and their Health (INDEPTH) Community in South Africa (HAALSI)".

Results

In total, 360 of 1932 male participants without depressive symptoms in wave 1 (24.3%) had incident depressive symptoms in wave 2 and 77 of 349 men had depressive symptoms in both waves 1 and 2 (persistent depressive symptoms). In all, 457 of 1258 male participants without low life satisfaction in Wave 1 (47.6%) had incident low life satisfaction in Wave 2, and 360 of 998 men had low life satisfaction at both Wave 1 and 2 (persistent low life satisfaction). In the unadjusted logistic regression analysis, having kidney disease and living with HIV had greater odds of incident depressive symptoms. In adjusted analysis, alcohol dependence (Adjusted Odds Ratio-AOR: 4.54, 95% Confidence Interval-CI: 1.05-19.66) was positively correlated and 1-7 and 8-11 years of education (AOR: 0.45, 95% CI: 0.27-0.74, and AOR: 0.20, 95% CI: 0.07-0.54, respectively) were negatively associated with persistent depressive symptoms. Increasing age increased the odds (AOR: 1.03, 95% CI: 1.01-1.04), while higher education (≥12 years) (AOR: 0.50, 95% CI: 0.33-0.76), and high physical activity (AOR: 0.68, 95% CI: 0.52-0.89) decreased the odds of incident low life satisfaction. Increasing age (AOR: 1.03, 95% CI: 1.02-1.04) and tobacco use (AOR: 1.64, 95% CI: 1.23-2.19) increased the odds and high physical activity (AOR: 0.73, 95% CI: 0.56-0.96) decreased the odds of persistent low life satisfaction.

Conclusions

Of the seven chronic conditions and five lifestyle factors evaluated, alcohol dependence increased the odds of persistent depressive symptoms and low physical activity, and tobacco use increased the odds of incident and/or persistent low life satisfaction among men in rural South Africa.

Predictors of and healthcare utilisation of depressive symptoms among middle-aged and older adults in Thailand: a national cross-sectional community-based study in 2015

OBJECTIVE

The prevalence of depressive symptoms and healthcare utilisation among the ageing population in Thailand is unclear. The study assessed the predictors of and healthcare utilisation of depressive symptoms among an ageing population in Thailand.

DESIGN

Cross-sectional, population-based study.

SETTING

National sample of people aged 45 years and older in Thailand from the 2015 Health, Ageing and Retirement in Thailand (HART) study.

PARTICIPANTS

The sample included 5135 individuals (≥45 years) with complete depressive symptoms data from the 2015 HART study.

OUTCOME MEASURES

Depressive symptoms were measured with the Centre for Epidemiological Studies Depression Scale. Logistic regression was used to estimate the associations between sociodemographic factors, health factors and depressive symptoms, and the associations between depressive symptoms and different types of healthcare utilisation.

RESULTS

The study population included 5135 participants with a median age of 66 years. The prevalence of depressive symptoms was 13.9%. The proportion of past 2 year hospital admission was 12.8%, hospital outpatient 49.7%, health centre outpatient 26.2%, private clinic 8.4%, traditional medical practitioner 2.8%, medical home visit 4.9% and past-year medical check-up 50.3%. In adjusted logistic regression analysis, low income, residing in the Southern region, history of a cardiovascular disease, brain diseases and/or psychiatric problems and functional disability were positively associated with depressive symptoms. Male sex, being a Buddhist, urban residence, high religious involvement, moderate and high physical activity were negatively associated with depressive symptoms. In fully adjusted logistic regression models, depressive symptoms were positively associated with hospital inpatient utilisation, hospital outpatient utilisation, health centre utilisation and utilisation of a traditional medicine practitioner.

CONCLUSIONS

More than one in 10 participants had depressive symptoms. Chronic conditions, sociodemographic factors, physical inactivity and low religious involvement increased the odds of depressive symptoms. Furthermore, depressive symptoms increased the odds of conventional and traditional healthcare utilisation.

Poor Self-Rated Oral Health Status and Associated Factors Amongst Adults in Algeria

BACKGROUND

Understanding the proportion and correlates of self-rated oral health (SROH) can assist in prioritising interventions. The aim of this study was to assess the prevalence of poor SROH and associated factors in a national community survey amongst adults in Algeria.

METHODS

This World Health Organisation (WHO) STEPS cross-sectional survey in Algeria in 2016 and 2017 included 6989 people (18-69 years; median age, 37 years) selected by multistage cluster sampling. The assessment included questionnaire information, physical measures, and biochemistry tests. The measures included questions on SROH, oral conditions, oral health behaviour, general health behaviour, and measures of health status.

RESULTS

The sample included 6989 people aged 18 to 69 years. Of the total sample, 17.1% had removable dentures, 35.5% had 0 to 19 natural teeth, 43.9% had dental pain in the past year, 40.5% had impaired oral health-related quality of life (OHRQoL), 26.9% cleaned their teeth 2 times/d or more, 79.6% used toothpaste, and 41.2% had visited a dentist in the past year. The prevalence of poor SROH was 37.3%. In the final logistic regression model, older age (45-69 years) (adjusted odds ratio [AOR], 1.34; 95% confidence interval [CI], 1.09-1.65), having removable dentures (AOR, 1.46; 95% CI, 1.14-1.87), dental pain (AOR, 2.16; 95% CI, 1.82-2.57), impaired OHRQoL (AOR, 2.69; 95% CI, 2.26-3.20), current smokeless tobacco use (AOR, 1.45; 95% CI, 1.12-1.89), and inadequate fruit and vegetable intake (AOR, 2.69; 95% CI, 2.26-3.20) increased the odds of poor SROH. Men (AOR, 0.76; 95% CI, 0.65-0.90), having 20 or more teeth (AOR, 0.35; 95% CI, 0.28-0.42), twice or more a day teeth cleaning (AOR, 0.72; 95% CI, 0.60-0.86), and using toothpaste (AOR, 0.67; 95% CI, 0.55-0.82) were protective against poor SROH.

CONCLUSIONS

Adults in Algeria reported a high prevalence of poor SROH, and several associated factors (sociodemographic, oral conditions, oral and general health-compromising behaviour) were found that can guide in oral health promotion strategies in Algeria.

Religiosity and Depression Among Community-Dwelling Older Adults in India: Results of a National Survey in 2017-2018

This study aimed to investigate the association between religiousness (affiliation, nonorganizational, organizational, and intrinsic religiosity) and major depressive disorder (MDD) and depressive symptoms among older adults in a national population survey in India. In total, 72,262 people (≥ 45 years) from the cross-sectional longitudinal aging study in India 2017-2018 responded to questions on religiosity, MDD, and depressive symptoms. Results indicate that 57.0% of participants were engaged in high nonorganizational (daily prayer) religiosity, 14.0% engaged in high (> 1/week or every day) organizational religiosity (attending religious services) and 34.9% had high intrinsic religiosity. In the adjusted logistic regression analysis, high nonorganizational religiosity (daily prayer), and high intrinsic religiosity were inversely associated with MDD. Similarly, high nonorganizational religiosity and high intrinsic religiosity were inversely associated with depressive symptoms. Organizational religiosity was not significantly associated with MDD or depressive symptoms. Compared to Hindus, Christians had lower odds of MDD and Sikhs had lower odds of depressive symptoms. High religiosity was observed among older adults in India. Nonorganizational and intrinsic religiosity were inversely associated with MDD and depressive symptoms.

High sedentary behavior and low physical activity among adults in Afghanistan: results from a national cross-sectional survey

Objective

The study aimed to evaluate the prevalence and correlates of sedentary behavior and combination of sedentary behavior and low physical activity among adults in Afghanistan in 2018.

Methods

This was a national representative cross-sectional study. The study utilized the data from Afghanistan STEPS survey 2018, where 3,956 adults (ages between 18 and 69 years) were interviewed at community-dwelling level. Using the Global Physical Activity Questionnaire, we have calculated the sedentary behavior and physical inactivity. Logistic regression was applied to investigate factors associated high sedentary behavior and low physical activity.

Results

Approximately half of the participants (49.8%) exhibited high levels of sedentary behavior, 40.3% low physical activity and 23.5% had both high sedentary behavior and low physical activity. Adjusted logistic regression analysis revealed that individuals who were employed (AOR: 0.34, 95% CI: 0.13-0.88) or self-employed (AOR: 0.60, 95% CI: 0.38-0.94) had significantly lower odds of both high SB and low physical activity than those whose work status was unpaid. Furthermore, older age (AOR: 1.75, 95% CI: 1.35-2.28), urban residence (AOR: 3.17, 95% CI: 1.72-6.05), having 4 or 5 adult household members (AOR: 1.77, 95% CI: 1.21-2.58) and being underweight (AOR: 1.78, 95% CI: 1.02-3.12) were found to be associated with high sedentary behavior. Moreover, factors such as female sex, having 4 or 5 or 6 or more adult household members, urban residence, overweight, and diabetes were positively associated, and male sex (AOR: 0.24, 95% CI: 0.12-0.51), being employed (AOR: 0.34, 95% CI: 0.13-0.88) or self-employed (AOR: 0.60, 95% CI: 0.38-0.94) were negatively associated with the occurrence of combination of high sedentary behavior and low physical activity.

Conclusion

Half of the participants had high sedentary behavior, and one in four had both high sedentary behavior and low physical activity together. These findings emphasize the importance of targeted interventions aimed at reducing sedentary behavior and promoting physical activity, particularly among vulnerable populations such as females, individuals from lower socioeconomic background, urban residents, and those with chronic conditions. Addressing these factors can contribute to improving public health outcomes and reducing negative health impacts of sedentary behavior in Afghanistan.

Trends in bio-behavioural risk factors of non-communicable diseases among adults in Sao Tome and Principe

Background

Understanding national trends in risk factors of noncommunicable diseases (NCDs) may have health policy implications. The aim of the study was to assess the prevalence and social and demographic factors associated with risk factors of NCDs in adults from 2008 to 2019 in Sao Tome and Principe.

Methods

In repeat cross-sectional national STEPS surveys 2,457 adults (median age 37 years) in 2008 and 1,893 adults (median age 38 years) in 2019 in Sao Tome and Principe responded to structured interviews, physical and biochemical measures. Logistic regressions were applied to estimate predictors of NCD risk factors.

Results

Having three to seven NCD risk factors significantly decreased among men but not women from 36.6% in 2008 to 26.8% in 2019. The proportion of specific risk factors of NCD increased significantly for low physical activity from 17.4% in 2008 to 30.9% in 2019, and overweight/obesity from 37.3% in 2008 to 51.0% in 2019. Insufficient fruit/vegetable consumption decreased from 83.1% in 2008 to 53.3% in 2019, frequent alcohol use from 32.6% in 2008 to 24.8% in 2019, and diabetes from 3.1% in 2008 to 1.2% in 2019, while the proportion of current tobacco use and hypertension remained unchanged from 2008 to 2019. Men engaged more often than women in current tobacco use and frequent alcohol use, and women had higher rates of low physical activity and overweight/obesity than men. Higher educational levels were positively associated with overweight/obesity, and inversely associated with frequent alcohol use and inadequate fruit/vegetable intake.

Conclusion

Between 2008 and 2019, the prevalence of seven risk factors for NCDs in Sao Tome and Principe declined among men, but not among women. Several associated variables have been identified for each individual risk factor of NCD that may help guide interventions.

Ten-year retrospect of the investigation of proximal limbs metastasis in cancer: a multi-center study on survival outcome, limb function status and surgical procedures analysis

BACKGROUND

The aim of study was to evaluate survival outcome and limb function in cancer patients with proximal limbs metastasis. Associated factors on survival outcome and limb function were identified. The comparative analysis between intramedullary nailing and prosthesis surgery in cancer patients with proximal limb metastasis was performed.

METHODS

In this five-center retrospective study, patients diagnosed with limbs metastasis were collected. Descriptive statistics was used and log-rank test was performed to analyze the survival in subgroups. The Cox proportional hazards regression analysis was performed to identify the independent prognostic factors. The Musculoskeletal Tumor Society (MSTS) scoring system was used to evaluate limb function after surgery, and t test or analysis of variance (ANOVA) was utilized in subgroup analysis.

RESULTS

A total of 316 patients with limb metastasis were included with mean age at 61.0 years. The most common primary tumor was breast, followed by renal cancer and lung cancer. The median overall survival was 24.0 months and the 1-, 3- and 5-year survival rates were 86.9%, 34.7% and 6.8%, respectively. Primary tumor type, visceral metastasis and chemotherapy were proved to be the independent prognostic factors. The mean Musculoskeletal Tumor Society (MSTS) score was 20.5, significant difference was observed in subgroup of solitary/multiple bone metastasis, with/without pathological fracture, and type of surgery.

CONCLUSION

The present study concluded that primary tumor type, visceral metastasis and chemotherapy were three factors affecting the survival of patients. Compared with intramedullary nailing, the patients underwent prosthesis surgery showed better limb function, this procedure should be encouraged in patients with indication.

Behavioural and biological risk factors of non-communicable diseases among adults in Cabo Verde: a repeated cross-sectional study of the 2007 and 2020 national community-based surveys

OBJECTIVE

The aim of the study is to estimate trends in the prevalence and associated factors of non-communicable disease (NCD) risk factors in adults from 2007 to 2020 in Cabo Verde.

DESIGN

Population-based cross-sectional study.

SETTING

Nationally representative samples of adult population in Cabo Verde from the 2007 and 2020 STEPwise approach to NCD risk factor surveillance (STEPS) surveys.

PARTICIPANTS

The sample included 1760 adults in 2007 and 3721 in 2020.

OUTCOME MEASURES

Included fruit/vegetable consumption, low physical activity, sedentary behaviour, current tobacco use, hazardous alcohol use, diabetes, total elevated cholesterol, hypertension and overweight/obesity. Logistic regressions adjusted for sociodemographic factors were applied to estimate predictors of each of the nine NCD risk factors.

RESULTS

Compared with participants in the study year 2007, participants in the study year 2020 had a significantly higher prevalence of low physical activity (adjusted OR (AOR): 2.21, 95% CI: 1.15 to 4.25) and overweight/obesity (AOR: 1.68, 95% CI: 1.26 to 2.23) and significantly lower rate of hypertension (AOR: 0.77, 95% CI: 0.64 to 0.93). Low physical activity (AOR: 1.61, 95% CI: 1.23 to 2.10), overweight/obesity (AOR: 2.59, 95% CI: 2.10 to 3.20), current tobacco use (AOR: 1.94, 95% CI: 1.36 to 2.75), hypertension (AOR: 5.45, 95% CI: 4.24 to 7.00), diabetes (AOR: 8.40, 95% CI: 4.65 to 15.18) and elevated total cholesterol (AOR: 4.58, 95% CI: 2.83 to 7.39) were more common among the 50-64-year-olds. Being male increased the odds of current tobacco use (AOR: 3.64, 95% CI: 2.75 to 4.81) and hazardous alcohol use (AOR: 4.79, 95% CI: 3.15 to 7.27), and decreased the odds of low physical activity (AOR: 0.48, 95% CI: 0.39 to 0.58) and overweight/obesity (AOR: 0.47, 95% CI: 0.40 to 0.56).

CONCLUSIONS

Of the nine NCD risk factors evaluated from 2007 to 2020 in Cabo Verde, two increased (overweight/obesity and low physical activity) and one decreased (hypertension). Several associated variables were identified for each individual NCD risk factor that can help in guiding interventions.

The association between psychosocial factors, protective factors, and its associated triggers with psychological distress among Bolivian adolescents

The purpose of this study is to investigate the association between psychosocial factors, protective factors, and its associated triggers with psychological distress among Bolivian adolescents. This cross-sectional study was conducted by investigating the 2018 Bolivia global school-based student health survey (GSHS). The total number of students who participated in this survey was 7931, and the final sample was 7377. The mean age of the participants was 15.3 years (SD = 1.4). Psychological distress was assessed with a 2-item screener (loneliness and worry induced sleep disturbance). In all 22.3% of participants reported experiencing psychological distress, with 18.1% among adolescent males and 26.2% among adolescent females. In adjusted logistic regression analysis (AOR, 95% CI), there are two significant directions of association. One is the negative association, such as parental involvement as a protective factor. School adolescents who had more parental involvement were less likely to experience psychological distress. Parents understand problems or worries (0.64, 0.54-0.75, p < .001) and parents disregard privacy (0.69, 0.58-0.82, p < .001). On the other hand, many psycho-social factors are significantly positively associated with psychological distress. School adolescents who experience more psychosocial factors are more likely to experience psychological distress. Physical assault in the previous year (1.83, 1.59-2.11, p < .001), being bullied at school (1.27, 1.07-1.52, p < .01), being bullied outside of school (1.36, 1.15-1.61, p < .001), and being cyberbullied (1.60, 1.37-1.88, p < .001), were all significantly associated with psychological distress. Healthy relationships in a family, and interventions to reduce violence and bullying, should be encouraged and promoted.

Trends in behavioral and biological risk factors for non-communicable diseases among adults in Bhutan: results from cross-sectional surveys in 2007, 2014, and 2019

Background

The study aimed to evaluate trends in the prevalence and correlates of risk factors for non-communicable diseases (NCDs; low physical activity, insufficient fruit/vegetable intake, current tobacco use, problem alcohol use, diabetes, hypertension, increased total cholesterol, and obesity) in Bhutan.

Methods

Three repeat cross-sectional Bhutan STEPS surveys (N = 9,281) in 2007, 2014, and 2019 were analyzed.

Results

The proportion of people with 3-8 NCD risk factors significantly decreased from 62.8% in 2007 to 32.6% in 2019 (p < 0.001), and the mean number of NCD risk factors significantly decreased from 3.0 in 2007 to 2.1 in 2019 (p < 0.001). In linear regression analyses by study year, older age (p < 0.001) was positively associated with eight NCD risk factors across all study years. Furthermore, male subjects were negatively (p < 0.01) and positively (p < 0.001) associated with eight NCD risk factors, respectively. Higher education levels (p < 0.05) were positively associated with eight NCD risk factors in 2007 and negatively associated with eight NCD risk factors in 2019 (p < 0.05). Employment (p < 0.001) and urban residence (p < 0.001) were positively associated with eight risk factors for NCD in 2019, while urban residence (p < 0.001) was negatively associated with eight NCD risk factors in 2014.

Conclusion

The prevalence of eight NCD risk factors decreased in Bhutan over the past 13 years. Inadequate fruit and vegetable intake, problem alcohol use, and hypertension increased, current tobacco use, low physical activity, obesity, diabetes, and elevated total cholesterol decreased from 2007 to 2019. Several factors associated for eight and each individual NCD risk factor were identified, which can help guide interventions.

Self-rated physical and mental health among older adults 80 years and older: cross-sectional results from a National community sample in Thailand

BACKGROUND

The aim of this study was to assess the self-reported physical health (SRPH) and self-reported mental health (SRMH) of older adults 80 years and older in Thailand.

METHODS

We analyze national cross-sectional data from the Health, Aging and Retirement in Thailand (HART) in 2015. Physical and mental health status was assessed by self-report.

RESULTS

The sample included 927 participants (excluding 101 proxy interviews), 80-117 years, median age 84 years [interquartile range (IQR) 81-86 years]. The median SRPH was 70.0 (IQR = 50.0-80.0), and median SRMH was 80.0 (IQR = 70.0 to 90.0). The prevalence of (good) SRPH was 53.3%, and the prevalence of (good) SRMH was 59.9%. In the final adjusted model, low or no income, living in the Northeastern, Northern and Southern region, daily activity limitations, moderate/severe pain, having one or two or more physical conditions, and low cognitive functioning were negatively associated, and higher physical activity was positively associated with good SRPH. No or low income, residing in the northern region of the country, daily activity limitations, low cognitive functioning, and probable depression were negatively associated with good SRMH, and physical activity was positively associated with good SRMH.

CONCLUSION

SRPH and SRMH was relatively high rated among the oldest old in Thailand, and influenced by various social, economic, and health-related factors. Special attention should be given to those with no or low income, those living in the non-central regions and those having no or low formal social engagement. Health care and other services should improve physical activity, financial support, and physical and mental care management to promote physical and mental well-being of older adults 80 years and older in Thailand.

Combined victimization of face-to-face and cyberbullying and adverse health outcomes among school-age adolescents in Argentina

Face-to-face bullying victimization (FBV) and cyber bullying victimization (CBV) are of global concern, including in Latin America. The aim of this study was to evaluate the associations between combined FBV and CBV relative to single victimization (FBV or CBV) and no victimization with a wide range of adverse health outcomes among school-aged adolescents from Argentina. National cross-sectional school data from 56,981 adolescents that responded to questions on FBV, CBV, and adverse health outcomes were analyzed. The results showed a prevalence of 18.7% FBV alone, 8.1% CBV alone and 13.6% combined FBV and CBV. Combined FBV and CBV had higher odds than single victimization (FBV or CBV) in 18 negative health outcomes, including anxiety, suicidal ideation, loneliness, suicide plan and attempt, smoking, smokeless tobacco use, history of intoxication, alcohol-related problems, current cannabis use, ever use of amphetamine, school truancy, participation in physical fighting, physically attacked, injury, ever sex, multiple sexual partners and sedentary behaviour. In conclusion, combined FBV and CBV had higher odds than single BV or no BV in most adverse health outcomes.

Trends in Behavioral and Biological Non-Communicable Diseases Risk Factors among Adults in Mongolia: Results from National Cross-Sectional Surveys in 2005, 2009, 2013 and 2019

Background

Understanding national trends in noncommunicable disease (NCD) risk factors may have health policy implications. We aimed to evaluate trends in the prevalence and correlates of eight risk factors for NCD from 2005 to 2019 in Mongolia.

Methods

Cross-sectional data were analyzed from 9,356 individuals (15-64/69 yr, mean age=37.3 yr) who participated in the Mongolia STEPS 2005, 2009, 2013 or 2019 surveys and had complete measurement of the risk factor for NCD.

Results

The proportion of having 3-8 NCD risk factors significantly decreased from 59.1% in 2005 to 49.4% in 2019, and the mean number of NCD risk factors significantly decreased from 2.8 in 2005 to 2.6 in 2019. In linear regression analyses by study year, older age and male sex were across all study years positively associated with eight NCD risk factors. The prevalence of low physical activity increased from 8.2% in 2005 to 28.4% in 2019, overweight/obesity from 49.6% in 2005 to 64.0% in 2019, and raised total cholesterol from 23.9% in 2005 to 27.6% in 2019, there was a significant decrease in inadequate fruit and vegetable intake from 85.1% in 2005 to 79.5% in 2019, current smoking from 26.6% in 2005 to 24.1% in 2019, hypertension from 28.2% in 2005 to 23.2% in 2019, while the prevalence of diabetes remained unchanged from 2005 to 2019.

Conclusion

The prevalence of eight risk factors for NCD decreased in the last 15 years in Mongolia. Several associated variables for eight and individual NCD risk factors were identified that can help guide interventions.

Prevalence and determinants of incident and persistent depressive symptoms among middle-aged and older adults in Thailand: prospective cohort study

BACKGROUND

There are no longitudinal studies investigating determinants of incident and persistent depressive symptoms in Southeast Asia.

AIMS

To estimate the proportion and correlates of incident and persistent depressive symptoms in a prospective cohort study among middle-aged and older adults (≥45 years) in Thailand.

METHOD

We analysed longitudinal data from the Health, Aging, and Retirement in Thailand (HART) surveys in 2015 and 2017. Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale. Logistic regression was used to calculate predictors of incident and persistent depressive symptoms.

RESULTS

In total, 290 of 4528 participants without depressive symptoms in 2015 had incident depressive symptoms in 2017 (9.8%) and 76 of 640 adults had persistent depressive symptoms (in both 2015 and 2017) (18.3%). In adjusted logistic regression analysis, having diabetes (adjusted odds ratio AOR = 1.48, 95% CI 1.07-2.05), musculoskeletal conditions (AOR = 1.56, 95% CI 1.01-2.41) and having three or more chronic conditions (AOR = 2.55, 95% CI 1.67-3.90) were positively associated and higher subjective economic status (AOR = 0.47, 95% CI 0.31-0.72) and social participation (AOR = 0.66, 95% CI 0.49-0.90) were inversely associated with incident depressive symptoms. Having a cardiovascular disease (AOR = 1.55, 95% CI 1.01-2.39) and having three or more chronic conditions (AOR = 2.47, 95% CI 1.07-5.67) were positively associated and social participation (AOR = 0.48, 95% CI 0.26-0.87) was inversely associated with persistent depressive symptoms.

CONCLUSIONS

One in ten middle-aged and older adults had incident depressive symptoms at 2-year follow-up. The prevalence of incident and/or persistent depression was higher in people with a lower subjective economic status, low social participation, diabetes, musculoskeletal disorders, cardiovascular conditions and a higher number of chronic diseases.

Prevalence and Correlates of Cardiovascular Health Status among Adults in Afghanistan: Results of a National Survey in 2018

Background

The aim of the study was to assess the prevalence and correlates of cardiovascular health (CVH) status among adults in Afghanistan.

Methods

In a national cross-sectional household survey 3,447 adults completed CVH measurements in Afghanistan. Criteria for ideal CVH (ICVH) were physical activity, healthy diet, non-smoking, fasting blood glucose (<100 mg/dL), body mass index (<25 kg/m²), total cholesterol (<200 mg/dL), and blood pressure (<120/<80 mmHg).

Results

More than one-third (34.3%) of participants had 5-7 ICVH, 45.7% 3-4 ICVH, and 20% had 0-2 ICVH. In adjusted logistic regression analysis, secondary or more education (AOR: 1.80, 95% CI: 1.22-2.66) was positively associated, and older age (45-69 years) (AOR: 0.33, 95% CI: 0.26-0.42), and urban residence (AOR: 0.67, 95% CI: 0.51-0.88) were inversely associated with 5-7 ICVH.

Conclusions

The prevalence of ICVH was low in Afghan adults. Population measures may be used to improve CVH targeting identified associated factors.

Clinicomics-guided distant metastasis prediction in breast cancer via artificial intelligence

BACKGROUND

Breast cancer has become the most common malignant tumour worldwide. Distant metastasis is one of the leading causes of breast cancer-related death. To verify the performance of clinicomics-guided distant metastasis risk prediction for breast cancer via artificial intelligence and to investigate the accuracy of the created prediction models for metachronous distant metastasis, bone metastasis and visceral metastasis.

METHODS

We retrospectively enrolled 6703 breast cancer patients from 2011 to 2016 in our hospital. The figures of magnetic resonance imaging scanning and ultrasound were collected, and the figures features of distant metastasis in breast cancer were detected. Clinicomics-guided nomogram was proven to be with significant better ability on distant metastasis prediction than the nomogram constructed by only clinical or radiographic data.

RESULTS

Three clinicomics-guided prediction nomograms on distant metastasis, bone metastasis and visceral metastasis were created and validated. These models can potentially guide metachronous distant metastasis screening and lead to the implementation of individualized prophylactic therapy for breast cancer patients.

CONCLUSION

Our study is the first study to make cliniomics a reality. Such cliniomics strategy possesses the development potential in artificial intelligence medicine.

Prevalence and associated factors of incident and persistent loneliness among middle-aged and older adults in Thailand

BACKGROUND

The aim of the study was to assess the prevalence and associated factors of incident and persistent loneliness in a prospective cohort study among middle-aged and older adults (≥ 45 years) in Thailand.

METHODS

Longitudinal data from the Health, Aging, and Retirement in Thailand (HART) study in 2015 and 2017 were analysed. Loneliness was assessed with one item from the Center for Epidemiological Studies Depression scale. Logistic regression was used to calculate predictors of incident and persistent loneliness.

RESULTS

In total, at baseline 21.7% had loneliness, 633 of 3696 participants without loneliness in 2015 had incident loneliness in 2017 (22.2%), and 239 of 790 adults had persistent loneliness (in both 2015 and 2017) (30.3%). In adjusted logistic regression analysis, low income (aOR: 1.27, 95% CI: 1.03 to 1.57), poor self-rated physical health status (aOR: 1.64, 95% CI: 1.27 to 2.12), hypertension (aOR: 1.34, 95% CI: 1.09 to 1.65), depressive symptoms (aOR: 1.97, 95% CI: 1.11 to 3.49), and having three or chronic conditions (aOR: 1.76, 95% CI: 1.19 to 2.60) were positively associated and a higher education (aOR: 0.74, 95% CI: 0.55 to 0.98) and living in the southern region of Thailand (aOR: 0.43, 95% CI: 0.30 to 0.61) were inversely associated with incident loneliness. Poor self-rated physical health status (aOR: 1.91, 95% CI: 1.26 to 2.88), and having three or more chronic diseases (aOR: 1.78, 95% CI: 1.07 to 2.98), were positively associated, and living in the southern region (aOR: 0.40, 95% CI: 0.25 to 0.65) was inversely associated with persistent loneliness.

CONCLUSION

More than one in five ageing adults had incident loneliness in 2 years of follow-up. The prevalence of incident and/or persistent loneliness was higher in people with a lower socioeconomic status, residing in the central region, poor self-rated physical health status, depressive symptoms, hypertension, and a higher number of chronic diseases.

Health risk behaviour and persistent and incident depression among middle-aged and older adults in South Africa

The aim of this study was to assess the association between five health risk behaviours and persistent and incident depressive symptoms in a longitudinal study in South Africa. The sample included 5059 men and women (≥40 years) in 2014/2015, and 4176 in 2018/2019 of the 'Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa'. Depressive symptoms were assessed with the Centre for Epidemiologic Studies Depression scale. Multivariable logistic regression analysis was conducted to assess the associations between five health risk behaviours and persistent and incident depressive symptoms. Results indicate that 5.0% of participants had depressive symptoms at both wave 1 and 2 (persistent depressive symptoms), and 27.9% had incident depressive symptoms in wave 2. Higher education and moderate baseline physical activity were negatively associated and those with cardiovascular disease were positively associated with persistent depressive symptoms. Middle wealth index was negative, and being HIV positive and baseline tobacco use were positively associated with incident depressive symptoms. In conclusion, of five health risk behaviours assessed (inadequate fruit/vegetable intake, alcohol dependence, tobacco use, physical activity, and sedentary behaviour), only moderate physical activity was protective against persistent depressive symptoms, and tobacco use was associated with incident depressive symptoms.

Tridirectional association between probable depression, fear of falling and falls among middle-aged and older adults in Thailand

PURPOSE

Depression is a major issue in the aging population, which may be related to fear of falling (FOF) and falls contributing to increased morbidity and mortality. The aim of the study was to assess the tridirectional associations between probable depression (PD), FOF and falls in a longitudinal study in Thailand.

METHODS

Longitudinal data of participants (≥45 years; N = 3708) from two consecutive waves (in 2015 and 2017) of the Health, Aging and Retirement in Thailand (HART) study were analysed. PD was assessed with the Center for Epidemiologic Studies Depression Scale, self-reported FOF and history of falls.

RESULTS

Having no PD in 2015 and PD in 2017 (aOR: 2.35, 95% CI: 1.67 to 3.30), and having both PD in 2015 and 2017 (aOR: 3.46, 95% CI: 1.92 to 6.23) were positively associated with incident FOF with activity avoidance, and no FOF in 2015 and FOF in 2017 (aOR: 2.29, 95% CI: 1.77 to 2.95), and both FOF in 2015 and 2017 (aOR: 2.38, 95% CI: 1.69 to 3.36) were positively associated with incident PD. Two or more falls in 2015 (aOR: 2.03, 95% CI: 1.29 to 3.19) was positively associated with incident PD, and both PD in 2015 and 2017 (aOR: 3.10, 95% CI: 1.40 to 6.48) were positively associated with incident multiple (≥2) falls.

CONCLUSIONS

We found tridirectional associations between PD, FOF and falls. It is suggested to screen and manage older adults for PD, FOF and fall history simultaneously.

Food insecurity is associated with multiple psychological and behavioural problems among adolescents in five Caribbean countries

The study aimed to assess associations between food insecurity and multiple psychological and behavioural problems among adolescents in five Caribbean countries. Data from national and cross-sectional school health surveys from 9,956 adolescents (15 years, median age) in Trinidad and Tobago, Suriname, Jamaica, Anguilla and the Dominican Republic in 2016-2017 were analyzed in 2016-2017. Results show that the prevalence of moderate (rarely or sometimes) past-month food insecurity was 35.9% and severe (mostly or always) food insecurity was 4.6%. Severe food insecurity among adolescents ranged from 2.9% in Dominican Republic to 11.2% in Suriname. In adjusted logistic regression analyses, the higher severity of food insecurity was associated with negative psychological outcomes (loneliness, suicidal ideation, suicide plan, suicide attempt, anxiety, current tobacco use and any trouble from alcohol use) and negative behavioural outcomes (truancy, bullied, physically attacked, physical injury, and multiple sexual partners). Two out of five adolescents experienced some form of food security. Food interventions, such as school feeding programmes, are warranted to reduce negative psychosocial outcomes.

Prevalence and associated factors of cross-sectional and incident self-reported arthritis or rheumatism among a national community sample of middle-aged and older adults in Thailand

Background

The study aimed to assess the prevalence and associated factors of cross-sectional and incident arthritis or rheumatism among a national community sample of middle-aged and older adults in Thailand.

Methods

We analyzed cross-sectional and longitudinal data from two consecutive waves (2015 and 2017) of the Health, Aging, and Retirement in Thailand (HART) study. Arthritis or rheumatism (SRA) was assessed by self-reported health care provider diagnosis.

Results

The cross-sectional (baseline) sample included 5,616 participants (≥45 years, median age 66 years, interquartile range 57 to 76 years) and the incident (follow-up) sample included 3,545 participants. The prevalence of SRA in the cross-sectional sample (baseline) was 4.0% and in the incident (follow-up) sample 5.3%. In the cross-sectional multivariable model, obesity class I (aOR: 1.78, 95% CI: 1.19 to 2.67), obesity class II (aOR: 1.82, 95% CI: 1.02 to 3.25), hypertension (aOR: 1.90, 95% CI: 1.35 to 2.66), brain disease and/or psychiatric problems (aOR: 4.79, 95% CI: 2.27 to 10.62), sleep problem (aOR: 1.45, 95% CI: 1.01 to 2.07) and prescription drug use (aOR: 1.63, 95% CI: 1.14 to 2.33) were positively associated, and not in the labor force (aOR: 0.53, 95% CI: 0.34 to 0.84), and employed (aOR: 0.63, 95% CI: 0.41 to 0.99) were negatively associated with SRA. In the incident multivariable model, obesity class I (aOR: 1.78, 95% CI: 1.17 to 3.61), obesity class II (aOR: 2.01, 95% CI: 1.12 to 3.61), poor mental health (aOR: 1.69, 95% CI: 1.19 to 2.41), and functional disability (aOR: 2.04, 95% CI: 1.01 to 4.13) were positively associated, and current alcohol use (aOR: 0.50, 95% CI: 0.25 to 0.99) was negatively associated with SRA.

Conclusion

The middle and older Thai adults had a low prevalence and incidence of SRA, and several physical and mental risk factors for cross-sectional and/or incident SRA were identified.

Lifestyle factors, mental health, and incident and persistent intrusive pain among ageing adults in South Africa

OBJECTIVES

The purpose of this study was to evaluate longitudinal associations with incident and persistent intrusive pain among rural South Africans.

METHODS

Longitudinal data from two consecutive waves in 2014/2015 and 2018/2019 in Agincourt, South Africa, were analysed. Pain was assessed with the Brief Pain Inventory.

RESULTS

In all, 683 adults of 3,628 participants without intrusive pain in Wave 1 (19.1%) had incident intrusive pain in Wave 2, 94 adults of 254 participants who had intrusive pain in Wave 1 (38.3%) had intrusive pain at both Wave 1 and 2 (persistent intrusive pain). Furthermore, 358 (7.2%) participants had intrusive pain at baseline. In the fully adjusted model for people without intrusive pain at baseline, the study found that obesity (AOR: 1.31, 95% CI: 1.05-1.63), depressive symptoms (AOR: 1.67, 95% CI: 1.34-2.08), PTSD (AOR: 1.71, 95% CI: 1.19-2.45), and poor sleep quality (AOR: 1.30, 95% CI: 1.04-1.62) were positively associated with incident intrusive pain. Older age was positively, and male sex and daily alcohol use were negatively associated with incident intrusive pain. Furthermore, in the final adjusted logistic regression model, this study found that older age was positively, and underweight, overweight, and high sedentary behavior were negatively associated with persistent intrusive pain.

CONCLUSIONS

Several modifiable risk factors for incident and/or persistent intrusive pain were identified.

Tobacco use and incident sleep parameters among a rural ageing population in South Africa

INTRODUCTION

Tobacco use may be associated with incident insomnia. The aim of the study was to investigate the association between tobacco use and incident sleep parameters in a longitudinal study in South Africa.

METHODS

Longitudinal data from two consecutive waves of middle-aged and older adults in 2014-2015 (n=5059) and 2018-2019 (n=4176) in rural South Africa were analyzed. Tobacco use and sleep parameters were assessed by self-report. The associations between tobacco use and incident sleep parameters were estimated with multivariable logistic regression.

RESULTS

The prevalence of baseline sleep parameters was poor sleep quality 6.5%, sleep disturbance 13.6%, restless sleep 32.9%, and breathing stops 7.0%. In the fully adjusted model for people without poor sleep quality at baseline, daily tobacco smoking, smoking ≥10 units of tobacco products, current tobacco use and current smokeless tobacco use did not increase the odds of incident poor sleep quality. Smoking ≥10 units of tobacco products in a day (AOR=3.83; 95% CI: 1.77-8.28), current tobacco use (AOR=1.65; 95% CI: 1.09-2.51), and daily tobacco smoking (AOR=2.16; 95% CI: 1.15-4.07), were significantly positively associated with incident sleep disturbance. Furthermore, incident restless sleep was significantly positively associated with smoking ≥10 units of tobacco products in a day (AOR=3.97; 95% CI: 1.18-13.37), current smokeless tobacco use (AOR=2.78; 95% CI: 1.17-6.62) and current tobacco use (AOR=2.00; 95% CI: 1.00-4.00). Incident breathing stops were significantly positively associated with daily smoking tobacco (AOR=2.08; 95% CI: 1.11-3.34), smoking 1-9 units of tobacco products in a day (AOR=2.17; 95% CI: 1.20-3.94), and current tobacco use (AOR=1.77; 95% CI: 1.16-2.72).

CONCLUSIONS

Higher tobacco use was independently associated with incident sleep disturbance, incident restless sleep, and incident breathing stops, but not with incident poor sleep quality.

Food insecurity and health outcomes among community-dwelling middle-aged and older adults in India

The study assessed associations between food insecurity and mental, physical, and behavioural health outcomes in India. The study analysed national cross-sectional population-based data (N = 72,262;  ≥ 45 years) from in India in 2017-2018. The overall prevalence of food insecurity was 9.7%. Food insecurity was significantly positively associated with poor mental health [low life satisfaction (AOR: 2.75, 95% CI 2.35-3.23), low self-reported health (AOR: 1.61, 95% CI 1.11-1.42), insomnia symptoms (AOR: 1.64, 95% CI 1.45-1.85), depressive symptoms (AOR: 2.21, 95% CI 1.97-2.48), major depressive disorder (AOR: 2.37, 95% CI 2.03-2.77), Alzheimer's/dementia (AOR: 1.75, 95% CI 1.13-2.69), and poorer cognitive functioning (AOR: 0.68, 95% CI 0.49-0.93)], poor physical health [bone or joint disease (AOR: 1.18, 95% CI 1.04-1.34), angina (AOR: 1.80, 95% CI 1.58-2.06), underweight (AOR: 1.28, 95% CI 1.16-1.40), chronic lung disease (AOR: 1.22, 95% CI 1.03-1.45), and functional disability (AOR: 1.68, 95% CI 1.47-1.92)], and health risk behaviour [tobacco use (AOR: 1.13, 95% CI 1.01-1.25), heavy episodic drinking (AOR: 1.45, 95% CI 1.10-1.91) and physical inactivity (AOR: 1.42, 95% CI 1.21-1.67)]. Furthermore, food insecurity was negatively associated with overweight/obesity (AOR: 0.80, 95% CI 0.73-0.88). Food insecurity was associated with seven poor mental health indicators, five poor physical health conditions, and three health risk behaviours. Programmes and policies that improve food availability may help improve mental and physical health among middle-aged and older adults in India.

Bidirectional Association Between Probable Depression and Multimorbidity Among Middle-Aged and Older Adults in Thailand

Introduction

The purpose of this study was to assess the bidirectional association between multimorbidity (MM) and probable depression in a longitudinal study in Thailand.

Methods

We analyzed longitudinal data of participants 45 years and older from two consecutive waves (in 2015 and 2017) of Health, Aging, and Retirement in Thailand (HART). Probable depression was assessed using the Center for Epidemiological Studies Depression scale. Logistic regression analysis was conducted to assess the association between baseline probable depression and incident physical MM, and baseline physical MM and incident probable depression.

Results

In all, 2712 participants without MM at baseline and 2684 without probable depression at baseline were included. At follow-up 15.6% of probable depression cases and 11.4% of nonprobable depression cases developed physical MM, and at follow-up 13.3% of physical MM cases and 8.9% of nonphysical MM cases developed probable depression. In the final logistic regression analysis, adjusted for age, sex, marital status, income, education, body mass index, physical activity, smoking tobacco, alcohol use, and social engagement, probable depression at baseline was positively associated with incident physical MM (aOR: 1.50, 95% CI: 1.09 to 2.06), and physical MM at baseline was positively associated with incident probable depression (aOR: 1.47, 95% CI: 1.07 to 2.02).

Discussion

Baseline physical MM increases the risk of incident probable depression and baseline probable depression increases the risk of incident physical MM among middle-aged and older adults in Thailand.

A Cross-Sectional and Longitudinal Study of Pain among Middle-Aged and Older Adults in Thailand

Objective

The present study aimed to assess the prevalence and risk factors of pain among ageing adults in Thailand.

Methods

Cross-sectional and longitudinal data were analysed from two consecutive national waves of the Health, Aging, and Retirement in Thailand (HART) study in 2015 and 2017. The dependent variable pain was defined as moderate or severe pain in any of the 13 areas of the body over the past month. Independent variables included sociodemographic factors, health risk behaviour, physical and mental health conditions, and healthcare utilization.

Results

The baseline or cross-sectional sample consisted of 5,616 participants (≥45 years), and the follow-up or incident sample consisted of 2,305 participants. The proportion of pain in the cross-sectional/baseline sample was 36.0%, and in the incident/follow-up sample 39.9%. In the cross-sectional/baseline multivariable model, poor self-reported mental health, sleep problem, arthritis or rheumatism, brain disease and/or psychiatric problems, lung disease, use of hospital in-patient, conventional out-patient, and traditional medicine practitioners were positively associated with pain. In the incident/follow-up multivariable model, older age, Buddhist religion, class I obesity, poor self-reported mental health, hospital in-patient, private clinic out-patient, and use of a practitioner of traditional medicine were positively associated with pain. Male sex and higher education were negatively associated with both cross-sectional and incident pain.

Conclusions

More than one-third of older adults in Thailand had past month moderate or severe pain. Risk factors of pain from cross-sectional and/or incident analysis included older age, female sex, lower education, obesity, poor self-reported mental health, sleep problem, arthritis or rheumatism, brain disease and/or psychiatric problems, lung disease, and conventional and traditional healthcare utilization.

Prevalence and correlates of major depressive disorder among a national sample of middle-aged and older adults in India

Objectives: This study aimed to assess the prevalence and correlates of major depressive disorder (MDD) among middle-age and older adults in India.Methods: The cross-sectional sample consisted of 72,262 persons (45 years and older) from the 2017 to 2018 Longitudinal Ageing Study in India (LASI) Wave 1. MDD is defined using DSM-5 criteria and measured with the CIDI-SF. Logistic regression was used to evaluate the associations with MDD.Results: The prevalence of past 12-month MDD was 7.6%, 8.1% among women and 7.0% among men, and 8.2% in persons 60 years and older. In the final adjusted model, food insecurity, having 3-6 discrimination experiences, ill-treatment, victim of violent crime, disaster exposure, unsafe home/neighbourhood, poor childhood health, hypertension, stroke, tobacco use, and physical pain were positively associated with MDD. Being male, married, high socioeconomic status, living in urban areas, high spirituality/religiosity, health insurance and medium social network were negatively associated with MDD.Conclusion: Almost one in ten middle-aged and older adults in India had MDD and several associated factors were identified.

Bidirectional association between functional disability and multimorbidity among middle-aged and older adults in Thailand

Objectives

The purpose of this study was to assess the bidirectional association between multimorbidity (MM) and functional disability among middle-aged and older adults in a longitudinal study in Thailand.

Methods

We analyzed longitudinal data of participants aged 45 years and older from two consecutive waves (in 2015 and 2017) of the Health, Aging, and Retirement in Thailand (HART). Functional disability was assessed with a 4-item activity of daily living (ADL) scale. Logistic regression analysis was conducted to assess the association between baseline functional disability and incident MM (≥2), and baseline morbidity and incident functional disability.

Results

The results indicate that a total of 1,716 individuals without morbidity at baseline and 3,529 without functional disability at baseline were included. At follow-up, 16.7 and 20.0% of functional disability cases and 7.1 and 3.6% of nonfunctional disability cases developed 2 morbidities and 3 or more morbidities, respectively, and 6.6% of MM cases and 4.0% of non-MM cases developed a functional disability. In the final logistic regression model adjusted for education, income, age, marital status, sex, smoking tobacco, body mass index (BMI), alcohol use, physical activity, and social engagement, functional disability at baseline was positively associated with incident MM (≥2) (adjusted odds ratio [aOR]: 2.58, 95% CI: 1.42-4.72), and MM (≥3) at baseline was positively associated with incident functional disability (aOR: 1.97, 95% CI: 1.13-3.43).

Conclusion

Multimorbidity and functional disability were bidirectionally associated.

Psychological and physical intimate partner violence and sexual risk behavior among South African couples: a dyadic analysis

This study aimed to examine intimate partner violence (IPV) as it relates to both partners' perceptions of IPV and sexual behaviors, considering how their IPV might be interdependent within the relationship dynamics. The sample consisted of 713 female-male dyads in which women were pregnant and living with HIV in rural South Africa. Using an actor-partner interdependence model (APIM), we examined the interdependent influence of psychological and physical IPV on men by their female partners and psychological and physical IPV on women by their male partners on sexual risk behavior. The APIM model found there were no actor (b = -0.06, SE = 0.05, p = .221) or partner (b = -1.2, SE = 0.06, p = .056) effects contributing to protected sex by female IPV victimization. In contrast, significant actor (b = -0.28, SE = 0.06, p < .001) and partner (b = -0.29, SE = 0.06, p < .001) effects for protection were related to male IPV victimization. The model also found that the covariate of female HIV disclosure was associated with both male (b = 0.5, SE = 0.12, p < .001) and female protected sexual intercourse (b = 0.58, SE = 0.1, p < .001). Female HIV disclosure was related to an increased likelihood of protected sex by both male and female partners. As male partners reported more IPV victimization, the likelihood of protected sex between male and female partners decreased.Trial registration: ClinicalTrials.gov identifier: NCT02085356.

Prevalence and factors associated with undiagnosed type 2 diabetes among adults in Iraq: analysis of cross-sectional data from the 2015 STEPS survey

OBJECTIVE

The purpose of the study was to assess the prevalence and correlates of undiagnosed type 2 diabetes (UT2D) among adults (aged 18 years and older) in Iraq.

DESIGN

Cross-sectional, population-based study.

SETTING

Nationally representative sample of general community-dwelling adult population in Iraq from the 2015 Iraq STEPS survey.

PARTICIPANTS

The sample included 3853 adults (mean age 41.8 years, SD=15.8), with complete fasting blood glucose values, from the 2015 Iraq STEPS survey.

OUTCOME MEASURES

Data collection included: (1) social and behavioural information, (2) physical parameters and blood pressure measurements and (3) biochemical measurements. UT2D was classified as not being diagnosed with T2D and fasting plasma glucose level ≥126 mg/dL. Multivariable multinomial and logistic regression was used to identify factors associated with UT2D.

RESULTS

The prevalence of UT2D was 8.1% and the prevalence of diagnosed T2D (DT2D) was 8.9%. Participants aged 50 years and older (adjusted relative risk ratio (ARRR): 2.11, 95% CI 1.30 to 3.43) and those with high cholesterol (ARRR: 1.54, 95% CI 1.05 to 2.24) had a higher risk of UT2D. Older age (≥50 years) (ARRR: 17.90, 95% CI 8.42 to 38.06), receipt of healthcare advice (ARRR: 2.15, 95% CI 1.56 to 2.96), history of cholesterol testing (ARRR: 2.17, 95% CI 1.58 to 2.99), stroke or heart attack (ARRR: 1.81, 95% CI 1.13 to 2.92), and high cholesterol (ARRR: 1.55, 95% CI 1.17 to 2.06) were positively associated with DT2D, and high physical activity (ARRR: 0.57, 95% CI 0.38 to 0.84) was negatively associated with DT2D. Higher than primary education (adjusted OR (AOR): 2.02, 95% CI 1.21 to 3.37) was positively associated with UT2D versus DT2D, while older age (≥50 years) (AOR: 0.12, 95% CI 0.06 to 0.25), healthcare advice (AOR: 0.45, 95% CI 0.29 to 0.70), and history of cholesterol screening (AOR: 0.37, 95% CI 0.24 to 0.58) were inversely associated with UT2D versus DT2D.

CONCLUSION

Almost one in ten adults in Iraq had UT2D, and various associated factors were identified that could be useful in planning interventions.

Factors affecting face mask-wearing behaviors to prevent COVID-19 among Thai people: A binary logistic regression model

OBJECTIVES

Face mask wearing is a standard preventive measure, in addition to handwashing and physical distancing. Individuals may find that wearing a face mask protects their physical health and prevents viral transmission. However, none of the studies in Thailand identified factors associated with face mask-wearing behaviors among Thai people. Therefore, this study aims to determine factors affecting face mask-wearing behaviors to prevent COVID-19.

METHODS

This research is analytical survey research. The data used in this study were under the project title "The assessment of psychosocial and behavioral response and compliance to restriction measures to prevent and control COVID-19: A series of the rapid survey." A total of 6,521 people participated in an online survey by multi-stage sampling. Bivariate logistic regression analysis was used to examine the factors associated with face mask-wearing behaviors.

RESULTS

After adjusting for independent variables (i.e., gender, age, education, career, smoking, and comorbidity disease), the bivariate logistic regression analysis revealed that gender, age, and career were statistically significant to the face mask-wearing behaviors (p < 0.05). Level of education, smoking, and comorbidity disease were not statistically significant with face mask-wearing behaviors among Thai people.

CONCLUSION

Further study should explore broader on individual face mask perceptions and wearing in the continuing of COVID-19 across gender, age, and careers to better understand their health behaviors and to inform further policy. In addition, the development of an intervention to promote face mask wearing should target men who age below 30 yrs. and did not work in government services careers as this group of the population was likely not to wear a face mask outside the home.

Mental distress and incident functional disability among a rural ageing population in South Africa

OBJECTIVES

The aim of the study was to investigate the association between mental symptoms and incident functional disability among middle-age and older adults in South Africa.

METHODS

Longitudinal data from two consecutive population surveys (2014/2015-2018/2019) in Agincourt, South Africa, were analysed.

RESULTS

In total, 298 of 3813 participants without functional disability in wave 1 (8.8%) had functional disability in wave 2. The prevalence of baseline functional disability was 9.1%. In the fully adjusted models for people without functional disability at baseline, depressive symptoms (AOR: 1.74, 95% CI: 1.08-2.80) among men and lower life satisfaction among men (AOR: 0.86, 95% CI: 0.80-0.93) and among women (AOR: 0.90, 95% CI: 0.83-0.98) increased the odds of incident functional disability. Posttraumatic stress disorder symptoms, poor sleep quality, restless sleep, and loneliness were not significantly associated with incident functional disability.

CONCLUSIONS

Depressive symptoms among men and lower life satisfaction among both sexes were independently associated with incident functional disability in ageing rural South Africans.

Longitudinal correlates of fruit and vegetable consumption with depressive symptoms among middle-aged and older adults in South Africa

BACKGROUND

Fruit and vegetable intake may influence mental well-being. The aim of this study was to assess longitudinal associations between fruit and vegetable intake and depressive symptoms among rural South Africans.

METHODS

This longitudinal community study enrolled 3,891 adults (≥ 40 years) from the "Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI)". Fruit and vegetable intake was assessed by self-report at wave 1, and depressive symptoms were assessed using the Center for Epidemiological Studies Depression Scale at wave 1 and 2. Outcomes were incident and persistent depressive symptoms at wave 2. Logistic regression was used to assess the associations between fruit and vegetable intake at wave 1 and incident, and persistent depressive symptoms.

RESULTS

Results indicate that in the fully adjusted model for individuals with no depressive symptoms at baseline, we found no significant association between frequency of fruit or vegetables intake and incident depressive symptoms. We also found no significant association between frequency of fruit or vegetable intake and persistent depressive symptoms.

CONCLUSION

Fruit and vegetable intake was not significantly associated with incident and persistent depressive symptoms.

Sleep duration and incident and persistent depressive symptoms among a rural ageing population in South Africa

BACKGROUND

The aim of the study was to assess the relationship between sleep duration and incident depressive symptoms (IDS) and persistent depressive symptoms (PDS) using longitudinal data from South Africa.

METHODS

This longitudinal community study enrolled 3891 adults (≥40 years) from the "Health and Ageing in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI)". Sleep duration was assessed by self-report at wave 1, and depressive symptoms were assessed using the Center for Epidemiological Studies Depression Scale at wave 1 and 2. Outcomes were incident and persistent depressive symptoms at wave 2. Multivariable logistic regression analysis was conducted to assess the associations between sleep duration at wave 1 and incident, and persistent depressive symptoms.

RESULTS

The prevalence of IDS was 25.6% and PDS 30.8%. The prevalence of very short, short, normal, and long sleep duration at baseline was 3.6%, 10.1%, 60.9% and 25.4%, respectively. In the fully adjusted model, long sleep duration was positively associated with IDS among men (AOR: 1.37, 95% CI: 1.02-1.84), but not among women (AOR: 0.91, 95% CI: 0.67-1.23). No models among both men and women showed a significant association between short sleep and IDS. Long sleep duration was associated with PDS (AOR: 2.04, 95% CI: 1.20-3.48) among men but not among women (AOR: 1.26, 95% CI: 0.76-2.11). Short sleep showed among both sexes no significant associations with PDS.

CONCLUSION

Long but not short sleep duration was independently associated with IDS and PDS among men but not among women.
