Employment conditions and mental health of overseas female migrant domestic workers in Hong Kong: a parallel mediation analysis.

BACKGROUND: Female migrant domestic workers (MDW), approximately 8.5 million globally, often live in their employer's home under vulnerable conditions. In Hong Kong, MDWs currently comprise 5% of the population. This study was conducted to assess the association between employment conditions and mental health, and the mediating roles stress and job satisfaction have, among female MDWs in Hong Kong. METHODS: Participants completed an online cross-sectional survey. A total of 1,965 survey were collected between August 2020 and August 2021. Questions in the survey were related to MDWs background information, employment conditions, stress, job satisfaction, and two mental health outcomes: anxiety and depression. An employment conditions score was created to assess the cumulative effect poor employment conditions had on mental health. A multicategorical parallel mediation analysis was used to assess the direct effect employment conditions have on mental health and the indirect effects through stress and job satisfaction. RESULTS: Overall, 17.7% of MDWs were reported to be suffering from anxiety and 30.8% from depression. An increase in poor employment conditions was statistically associated with an increase in both outcomes, while stress levels and job satisfaction mediated this association. CONCLUSIONS: The findings call for increased scrutiny of employment conditions and mental well-being of MDWs.

Sociodemographic moderation of the association between depression and stroke incidence in a retrospective cohort of 0.4 million primary care recipients with hypertension.

BACKGROUND: Previous research has suggested an association between depression and subsequent acute stroke incidence, but few studies have examined any effect modification by sociodemographic factors. In addition, no studies have investigated this association among primary care recipients with hypertension. METHODS: We examined the anonymized records of all public general outpatient visits by patients aged 45+ during January 2007-December 2010 in Hong Kong to extract primary care patients with hypertension for analysis. We took the last consultation date as the baseline and followed them up for 4 years (until 2011-2014) to observe any subsequent acute hospitalization due to stroke. Mixed-effects Cox models (random intercept across 74 included clinics) were implemented to examine the association between depression (ICPC diagnosis or anti-depressant prescription) at baseline and the hazard of acute stroke (ICD-9: 430-437.9). Effect modification by age, sex, and recipient status of social security assistance was examined in extended models with respective interaction terms specified. RESULTS: In total, 396 858 eligible patients were included, with 9099 (2.3%) having depression, and 10 851 (2.7%) eventually hospitalized for stroke. From the adjusted analysis, baseline depression was associated with a 17% increased hazard of acute stroke hospitalization [95% confidence interval (CI) 1.03-1.32]. This association was suggested to be even stronger among men than among women (hazard ratio = 1.29, 95% CI 1.00-1.67). CONCLUSION: Depression is more strongly associated with acute stroke incidence among male than female primary care patients with hypertension. More integrated services are warranted to address their needs.

Differential associations among social support, health promoting behaviors, health-related quality of life and subjective well-being in older and younger persons: a structural equation modelling approach.

BACKGROUND: Extensive studies have confirmed social support as a critical protective factor of people's health-related quality of life (HRQoL) and subjective well-being (SWB). However, health promoting behaviors as a potential mechanism and age differences in this mechanism has received fewer attention. This study aims to examine the associations among social support, health promoting behaviors, HRQoL and SWB in older and younger persons in Hong Kong. METHOD: A convenience sample of both younger (12-35 years old) and older persons (55 years old and above) were recruited from three non-government organizations to complete a survey. Structural Equation Model (SEM) was conducted to test both the measurement model and structural models to examine the relationship between social support, health promoting behaviors, HRQoL and SWB. Multi-group SEM was also performed and compared to test whether there were significant age differences in the pathways between the key variables. RESULTS: A final sample of 408 participants (older-persons: N = 200 (mean age: 71.63 (8.16); 180/200 female), younger-persons: N = 208 (mean age: 18.10 (5.04); 155/208 female) were included in the final analysis. Results showed that social support was positively associated with SWB directly and indirectly through health promoting behaviors for the whole sample (CFI = .95, IFI = .94, RMSEA = .07, SRMR = 0.056). Results suggested that the association between the variables differed across age samples. While social support showed a positive association with health promoting behaviors for both younger and older persons, how each of them associated with HRQoL and SWB was different. CONCLUSION: Findings suggest that the pathway which social support linked with HRQoL and SWB might differ across age groups. Age-specific strategies should be considered when promoting HRQoL and SWB among the younger and older population.

Socioeconomic Patterns of COVID-19 Clusters in Low-Incidence City, Hong Kong.

Although coronavirus disease (COVID-19) outbreaks have been relatively well controlled in Hong Kong, containment remains challenging among socioeconomically disadvantaged persons. They are at higher risk for widespread COVID-19 transmission through sizable clustering, probably because of exposure to social settings in which existing mitigation policies had differential socioeconomic effects.

Differential educational patterning of cardiometabolic risks between women and men among community-dwelling Chinese adults in Hong Kong: the mediating role of obesity.

OBJECTIVES: Educational inequalities in cardiometabolic diseases (CMD) are globally recognised; nonetheless, the evidence on potential explanatory mechanisms and effective strategies for CMD prevention and inequality reduction is relatively scarce in Asia. Therefore, the current study examined the extent and potential mediators of the association of education level with CMD conditions (i.e., hypertension and diabetes) in an advanced economy in Asia. DESIGN: A cross-sectional study. SETTING: This territory-wide cross-sectional Population Health Survey in 2014-2015 was performed in Hong Kong. Demographic, socio-economic and lifestyle factors were collected via questionnaire, while clinical data on blood pressure and glucose levels, lipid profiles and anthropometric measures were obtained during health examination. Hypertension and diabetes statuses were objectively defined by both clinical data and the use of relevant medications. PARTICIPANTS: 2297 community-dwelling adults aged between 15-84 years recruited via systematic replicated sampling of living quarters. RESULTS: Multivariable binary logistic regression analysis showed that lower education level was significantly associated with hypertension among women but not men, whereas similar pattern was also observed for diabetes and other related clinical risk factors. Also, general and abdominal obesity were independently associated with hypertension and diabetes among both women and men, and substantially mediated the observed inequalities across education levels among women. Specifically, abdominal obesity was a particularly strong risk factor and mediator for diabetes. CONCLUSION: Educational patterning of CMD was more apparent among women in Hong Kong. Obesity control appears to be important for both overall CMD prevention and reduction of educational inequalities in CMD among women.

Comparison of adaptive versions of the Hong Kong-specific criteria and 2015 Beers criteria for assessing potentially inappropriate medication use in Hong Kong older patients.

BACKGROUND: The Hong Kong-specific criteria have been established in 2019 to assess potentially inappropriate medication (PIM) use in older adults and improve the local prescribing quality. The aim of this study was to compare the adaptive versions of the Hong Kong-specific criteria and 2015 Beers criteria for assessing the prevalence and correlates of PIM use in Hong Kong older patients. METHODS: A cross-sectional study was performed from January 1, 2014 to December 31, 2014 using the Hospital Authority (HA) database. A total of 489,301 older patients aged 65 years and older visiting general outpatient clinics (GOPCs) during the study period were included in the study. Two categories of PIM use included in the Hong Kong-specific criteria and 2015 Beers criteria, i.e. PIMs independent of diagnoses and PIMs considering specific medical conditions, were adapted to assess the prevalence of PIM use among the study sample. Characteristics of PIM users and the most frequently prescribed PIMs were investigated for each set of the criteria. Factors associated with PIM use were identified using the stepwise multivariable logistic regression analysis. RESULTS: The adaptive Hong Kong-specific criteria could detect a higher prevalence of patients exposed to at least one PIM than that assessed by the adaptive Beers criteria (49.5% vs 47.5%). Meanwhile, the adaptive Hong Kong-specific criteria could identify a higher rate of patients exposed to PIMs independent of diagnoses (48.1% vs 46.8%) and PIMs considering specific medical conditions (7.3% vs 4.9%) compared with that of the adaptive Beers criteria. The most frequently prescribed PIMs detected by the adaptive Beers criteria were all included in the adaptive Hong Kong-specific criteria. The strongest factor associated with PIM use was number of different medications prescribed. Patients with female gender, aged 65 ~ 74 years, a larger number of GOPC visits, and more than six diagnoses were associated with greater risk of PIM use, whereas advancing age was associated with lower risk of PIM use. CONCLUSIONS: The adaptive Hong Kong-specific criteria could detect a higher prevalence of PIM use than the adaptive Beers criteria in older adults visiting GOPCs in Hong Kong. It is necessary to update the prevalence and correlates of PIM use regularly in older adults to monitor the burden of PIM use and identify vulnerable patients who need further interventions.

Association between antipsychotic use and acute ischemic heart disease in women but not in men: a retrospective cohort study of over one million primary care patients.

BACKGROUND: Research comparing sex differences in the effects of antipsychotic medications on acute ischemic heart disease (IHD) is limited and the findings ambiguous. This study aimed to investigate these associations within a primary care setting. METHODS: Hong Kong public general outpatient electronic records of patients aged 45+ during 2007-2010 were extracted, with the last consultation date as the baseline for a 4-year follow-up period to observe acute IHD hospitalizations (2011-2014). Antipsychotic use was defined as any prescription over the previous 12 months from a list of 16 antipsychotics, while acute IHD was defined by ICD-9: 410.00-411.89. Both sex-specific and sex-combined (both sexes) mixed-effects Cox models (random intercept across 74 clinics) were implemented to examine the association and test the interaction between antipsychotics and sex. RESULTS: Among 1,043,236 included patients, 17,780 (1.7%) were prescribed antipsychotics, and 8342 (0.8%) developed IHD. In sex-specific analyses, antipsychotic prescription was associated with a 32% increased hazard rate of acute IHD among women (95% CI 1.05-1.67) but not among men. A likelihood ratio test comparing sex-combined models with and without the interaction between antipsychotic use and sex suggested significant interaction (χ2 = 4.72, P = 0.030). The association between antipsychotic use and IHD among women attenuated and became non-significant when haloperidol was omitted from the operationalization of antipsychotic use (HR = 1.23, 95% CI 0.95-1.60). CONCLUSION: Our results suggest that antipsychotic prescription is moderately associated with an increased risk of acute IHD among women in primary care and this relationship may be explained by specific antipsychotics. Further research should observe and capture the potential intermediary mechanisms and the dose-response relationship of this association to provide more rigorous evidence to establish causality and inform clinical practices.

Socioeconomic disadvantages over the life-course and their influence on obesity among older Hong Kong Chinese adults.

BACKGROUND: The life-course perspective on socioeconomic inequality in health is a burgeoning field of research. Nonetheless, the three classic life-course models (i.e. sensitive period, cumulative risk and social mobility models) have rarely been simultaneously applied to studies on obesity. Therefore, this study examined the associations of socioeconomic positions (SEPs) across life stages and their associated life-course models with both general and abdominal obesity. METHODS: Face-to-face interviews were conducted among 1077 community-dwelling adults aged 50 or above during 2014-15 in Hong Kong. Experiences of poverty, educational attainment and deprivation of necessities represented respondents' SEP in childhood, early adulthood and late adulthood, respectively. General and abdominal obesity were defined as body mass index ≥25 kg m-2 and waist-to-height ratio >0.5. Multivariable modified Poisson regression with a robust error variance was performed. RESULTS: Respondents with low childhood SEP tended to have reduced risk of general obesity [relative risk (RR) = 0.85; 95% confidence interval (CI) = 0.72-1.00], whereas those with low childhood SEP and low late-adulthood SEP tended to have increased risk of abdominal obesity (RR = 1.10; 95% CI = 1.00-1.21 and RR = 1.14; 95% CI = 1.03-1.26, respectively). Cumulative socioeconomic disadvantages showed a dose-response relationship with abdominal obesity. Also, those with upward socioeconomic mobility had lower risk of abdominal obesity, whereas those with downward socioeconomic mobility had greater risk. CONCLUSIONS: Low SEP, especially in childhood, exerted contrasting effects on general and abdominal obesity among older Hong Kong Chinese adults. The three life-course models operated simultaneously in determining the risk of abdominal obesity, while support for cumulative risk and social mobility models was weak in general obesity.

Collaborate across silos: Perceived barriers to integration of care for the elderly from the perspectives of service providers.

PURPOSE: To examine the barriers that hinder collaboration between health care and social care services and to report recommendations for effective collaboration to meet the growing support and care needs of our ageing population. METHODS: Data for this qualitative study were obtained from interviews with 7 key informants (n = 42) and 22 focus groups (n = 117) consisting of service providers who were from the health care or social care sectors and supporting elderly patients with multiple chronic diseases or long-term care needs. Data collection was conducted from 2015 to 2016. The data were analysed using an inductive approach on the basis of thematic analysis. FINDINGS: Qualitative analysis reviewed a number of factors that play a significant role in setting up barriers at the operational level, including fragmentation and lack of sustainability of discharge programmes provided by non-governmental organisations, lack of capacity of homes for the elderly, limitation of time and resources, and variation of roles in supporting end-of-life care decisions between the medical and social sectors. Other barriers are those of communication to be found at the structural level and perceptual ones that exist between professionals. Of these, perceptual barriers affect attitudes and create mistrust and interprofessional stereotypes and a hierarchy between the health care and social care sectors. CONCLUSION: Health care and social care service providers recognise the need for collaborative work to enhance continuity of care and ageing in place; however, their efforts are hindered by the identified barriers that need to be dealt with in practical terms and by a change of policy.

Integrated care for older populations and its implementation facilitators and barriers: A rapid scoping review.

PURPOSE: Inform health system improvements by summarizing components of integrated care in older populations. Identify key implementation barriers and facilitators. DATA SOURCES: A scoping review was undertaken for evidence from MEDLINE, the Cochrane Library, organizational websites and internet searches. Eligible publications included reviews, reports, individual studies and policy documents published from 2005 to February 2017. STUDY SELECTION: Initial eligible documents were reviews or reports concerning integrated care approaches in older/frail populations. Other documents were later sourced to identify and contextualize implementation issues. DATA EXTRACTION: Study findings and implementation barriers and facilitators were charted and thematically synthesized. RESULTS OF DATA SYNTHESIS: Thematic synthesis using 30 publications identified 8 important components for integrated care in elderly and frail populations: (i) care continuity/transitions; (ii) enabling policies/governance; (iii) shared values/goals; (iv) person-centred care; (v) multi-/inter-disciplinary services; (vi) effective communication; (vii) case management; (viii) needs assessments for care and discharge planning. Intervention outcomes and implementation issues (barriers or facilitators) tend to depend heavily on the context and programme objectives. Implementation issues in four main areas were observed: (i) Macro-level contextual factors; (ii) Miso-level system organization (funding, leadership, service structure and culture); (iii) Miso-level intervention organization (characteristics, resources and credibility) and (iv) Micro-level factors (shared values, engagement and communication). CONCLUSION: Improving integration in care requires many components. However, local barriers and facilitators need to be considered. Changes are expected to occur slowly and are more likely to be successful where elements of integrated care are well incorporated into local settings.

COHORT EFFECTS OF SUICIDE MORTALITY ARE SEX SPECIFIC IN THE RAPIDLY DEVELOPED HONG KONG CHINESE POPULATION, 1976-2010.

BACKGROUND: To examine temporal variations of age, period, and cohort on suicide mortality rate in Hong Kong (HK) from 1976 to 2010, and speculate the macroenvironmental mechanisms of the observed trends. METHODS: Poisson age-period-cohort modeling was used to delineate the effects of age, period, and cohort on suicide mortality. Analysis by sex was also conducted to examine if gender difference exists for suicidal behaviours. RESULTS: Age-cohort model provides the best fit to the mortality data, implying that the cohort effect is likely to explain more of the contributions to HK's suicide mortality pattern than the period effect. Risk of suicide mortality increases nonlinearly with age and accelerates after age 65-69 for both sexes. Moreover, the cohort effects differ between the sexes-risk of mortality increases continually for men born after 1961, but no change is observed for women since the 1941 cohort. CONCLUSIONS: With increased risk of suicide mortality in younger cohorts and the age effect of suicide mortality, we may see future increase in suicide mortality as these younger cohorts age. Further studies are needed to clarify plausible associations between broader sociohistorical changes in the population impacting psychological risk factors and suicidal behaviour to better inform suicide prevention strategies.

Erectile Dysfunction is Associated with Subsequent Cardiovascular and Respiratory Mortality in Cohort of 1,436 Chinese Elderly Men.

INTRODUCTION: Erectile dysfunction (ED) is commonly shown to be associated with subsequent cardiovascular mortality, but not respiratory mortality, despite respiratory disease being highly prevalent among ED patients. AIM: We aim to examine associations of ED with all-cause and cause-specific (i.e., cardiovascular and respiratory) mortality in a prospective cohort of 1,436 Chinese men, followed up from 2001 for a median of 11.5 years. METHODS: ED measurement was based on a single question of four categories at the 4-year follow up. MAIN OUTCOME MEASURES: Outcome measures include all-cause and cause-specific mortality (i.e., cardiovascular and respiratory mortality, classified according to the International Classification of Disease-version 10 [ICD-10]). Multivariable regression models estimated associations between ED and all-cause and cause-specific mortality, adjusting for the presence of chronic conditions, and socio-demographics and lifestyle factors. For each category of disease-specific mortality, subjects with the corresponding diseases and death cases from other causes were excluded. Cancer mortality was included for comparison. RESULTS: Participants who were completely impotent had significantly increased risk of all-cause (HR = 1.63, 95% CI = 1.20-2.23), cardiovascular (HR = 3.94, 95% CI = 1.77-8.76) and respiratory mortality (HR = 3.16, 95% CI = 1.46-6.81) compared with non-impotent participants, adjusting for chronic conditions, and socio-demographics and lifestyle factors. CONCLUSION: ED is significantly associated with subsequent all-cause mortality, possibly via its association with cardiovascular and respiratory mortality. Primary care practitioners should pay attention to ED patients' cardiovascular and respiratory risk profiles, which may benefit their prognosis.

Inequalities in health status among rural residents: EQ-5D findings from household survey China.

INTRODUCTION: This study analyzed inequalities in health status among different socioeconomic and demographic rural residents covered by the New Rural Cooperative Medical System in China. METHODS: A cross-sectional study was conducted in Lian Yungang City, China. A total of 337 respondents, who were selected by using a multistage stratified systematic random sampling method, completed the surveys. A questionnaire consisting of EQ-5D and demographic and socioeconomic information was adopted for data collection, and was administered by face-to-face interviews. Multiple regression models were employed to examine the differences in the Visual Analogue Scale (VAS) score and the EQ-5D dimensions. RESULTS: Compared with those with lower education attainment, the respondents with higher education levels tended to report a higher VAS score (ß = 2.666, 95% CI: 0.978 to 6.310), and were less likely to suffer from pain/discomfort (OR = 3.968; 95% CI: 1.447 to 10.880). The singles were more likely than the married to report moderate or extreme problems in usual activities (OR = 4.583; 95% CI: 1.188 to 17.676) and mobility (OR = 10.666; 95% CI: 2.464 to 6.171). However, no statistically significant differences were identified between the respondents with different income levels in the VAS score and EQ-5D dimensions. CONCLUSIONS: This study suggests that the singles and the people with lower education levels are high-risk groups for poorer health status in the Chinese rural population. The findings from this study warrant further investigation.

Determinants of COVID-19 Vaccine Uptake among Female Foreign Domestic Workers in Hong Kong: A Cross-Sectional Quantitative Survey.

Globally, minority groups and non-citizens may not be sufficiently included in the COVID-19 vaccine coverage. This study seeks to understand determinants of vaccine uptake among female foreign domestic workers (FDWs) in Hong Kong. We conducted a cross-sectional study of female FDWs (n = 581) from June to August 2021. Respondents completed an online survey obtaining sociodemographic, employment, and health status information. Based upon the socio-ecological model, we obtained individual, interpersonal, and socio-structural factors that may be associated with COVID-19 vaccine uptake. Multivariable logistic regression analysis was used to examine factors associated with having received at least one dose of a COVID-19 vaccine. At the individual level, agreeing that taking COVID-19 vaccines can contribute to COVID-19 control in Hong Kong (OR 6.11, 95% CI 2.27-16.43) was associated with increased vaccine uptake, while being worried of severe side-effects from vaccination (OR 0.29, 95% CI 0.16-0.55) was associated with decreased uptake. At the interpersonal level, those being encouraged by their employer (OR 2.05, 95% CI 1.06-3.95) and family members (OR 2.27, 95% CI 1.17-4.38) were more likely to be vaccinated, while at the socio-structural level, believing vaccination would violate religious beliefs (OR 0.19, 95% CI 0.06-0.65) was associated with decreased uptake. The government can formulate a multi-level approach according to our findings to target the remaining unvaccinated FDW population.

Comparing Multimorbidity Patterns Among Discharged Middle-Aged and Older Inpatients Between Hong Kong and Zurich: A Hierarchical Agglomerative Clustering Analysis of Routine Hospital Records.

Background: Multimorbidity, defined as the co-occurrence of ≥2 chronic conditions, is clinically diverse. Such complexity hinders the development of integrated/collaborative care for multimorbid patients. In addition, the universality of multimorbidity patterns is unclear given scarce research comparing multimorbidity profiles across populations. This study aims to derive and compare multimorbidity profiles in Hong Kong (HK, PRC) and Zurich (ZH, Switzerland). Methods: Stratified by sites, hierarchical agglomerative clustering analysis (dissimilarity measured by Jaccard index) was conducted with the objective of grouping inpatients into clinically meaningful clusters based on age, sex, and 30 chronic conditions among 20,000 randomly selected discharged multimorbid inpatients (10,000 from each site) aged ≥ 45 years. The elbow point method based on average within-cluster dissimilarity, complemented with a qualitative clinical examination of disease prevalence, was used to determine the number of clusters. Results: Nine clusters were derived for each site. Both similarities and dissimilarities of multimorbidity patterns were observed. There was one stroke-oriented cluster (3.9% in HK; 6.5% in ZH) and one chronic kidney disease-oriented cluster (13.1% in HK; 11.5% ZH) in each site. Examples of site-specific multimorbidity patterns, on the other hand, included a myocardial infarction-oriented cluster in ZH (2.3%) and several clusters in HK with high prevalence of heart failure (>65%) and chronic pain (>20%). Conclusion: This is the first study using hierarchical agglomerative clustering analysis to profile multimorbid inpatients from two different populations to identify universalities and differences of multimorbidity patterns. Our findings may inform the coordination of integrated/collaborative healthcare services.

How does socioeconomic development affect risk of mortality? An age-period-cohort analysis from a recently transitioned population in China.

During the 20th century, the Hong Kong Chinese population experienced 2 abrupt but temporally distinct macroenvironmental changes: The transition from essentially preindustrial living conditions to a rapidly developing economy through mass migration in the late 1940s was followed by the emergence of an infant and childhood adiposity epidemic in the 1960s. The authors aimed to delineate the effects of these 2 aspects of economic development on mortality, thus providing a sentinel for other rapidly developing economies. Sex-specific Poisson models were used to estimate effects of age, calendar period, and birth cohort on Hong Kong adult mortality between 1976 and 2005. All-cause and cause-specific mortality, including mortality from ischemic heart disease (IHD), cardiovascular disease excluding IHD, lung cancer, other cancers, and respiratory disease, were considered. Male mortality from IHD and female mortality from other cancers increased with birth into a more economically developed environment. Cardiovascular disease mortality increased with birth after the start of the infant and childhood adiposity epidemic, particularly for men. Macroenvironmental changes associated with economic development had sex-specific effects over the life course, probably originating in early life. The full population health consequences of these changes are unlikely to manifest until persons who have spent their early lives in such environments reach an age at which they become vulnerable to chronic diseases.

Prospective Association of Obesity Patterns with Subclinical Carotid Plaque Development in Early Postmenopausal Chinese Women.

OBJECTIVE: This study aimed to examine the prospective associations of general and abdominal obesity patterns with carotid plaque development among early postmenopausal Chinese women. METHODS: A total of 518 postmenopausal women aged 50 to 64 years were recruited between 2002 and 2004 and were followed up at 3 years and 5 years. Carotid plaque was measured using B-mode ultrasonography, whereas general and abdominal obesity were defined as BMI ≥ 25 kg/m2 and waist-hip ratio ≥ 0.85, respectively. Sociodemographic, lifestyle, mental health, disease history, and clinical measurements were also assessed for confounding control. Multivariable binary logistic regression analyses on plaque development at 5 years were performed among 322 women with no carotid plaque at baseline. RESULTS: Over the 5-year follow-up period, 70 women (21.7%) developed carotid plaque. Baseline abdominal obesity independently predicted plaque development (adjusted odds ratio = 2.30; 95% CI: 1.15-4.60), but general obesity did not. Women with normal-weight abdominal obesity were more than twice as likely to develop carotid plaque (adjusted odds ratio = 2.43; 95% CI: 1.02-5.75) compared with women with no obesity, with their risk comparable to women with both general and abdominal obesity. CONCLUSIONS: Abdominal obesity was a critical predictor of subclinical carotid plaque development among early postmenopausal Chinese women. Policy makers should recognize the need to identify high-risk midlife women with normal-weight abdominal obesity in public health and clinical practice.

Accelerated progression of waist-to-hip ratio but not body mass index associated with lower socioeconomic position: a cohort study of nonobese early postmenopausal Chinese women.

OBJECTIVE: Menopausal changes are linked to increase in body fat mass and central fat distribution; nonetheless, the impact of socioeconomic position on such changes has rarely been examined. This cohort study assessed the temporal associations of socioeconomic position with changes in body mass index (BMI) and waist-to-hip ratio (WHR) among early postmenopausal women. METHODS: Between 2002 and 2004, 518 Hong Kong Chinese women aged 50 to 64 and within 10 years since menopause were recruited and followed up at 3 and 5 years. Weight, height, and waist and hip circumferences were measured by trained interviewers at baseline and follow-up interviews. Socioeconomic positions including educational attainment, economic activity status and household income level, and other baseline demographic characteristics, lifestyle behaviors, and mental health status were collected based on a structured questionnaire. In total, 287 and 267 women with no general and abdominal obesity, respectively, at baseline were included in multiple regression analyses. RESULTS: Mean intrapersonal increases in BMI and WHR between baseline and 5-year interview were 0.46 kg/m and 2.80%, respectively. Women with no secondary education were 75% more likely to have a greater than-mean WHR increase than their more educated counterparts (P = 0.039). Also, having no secondary education (P = 0.041) and being a homemaker (P = 0.034) had accelerated surge in WHR. Nonetheless, baseline socioeconomic positions were not significantly associated with BMI changes. CONCLUSIONS: Socioeconomic patterning was observed for the progression of WHR among nonobese Chinese women soon after menopause. Early postmenopausal stage may be a critical window for prevention of abdominal obesity among women with a lower educational attainment.

Long-term care cost drivers and expenditure projection to 2036 in Hong Kong.

BACKGROUND: Hong Kong's rapidly ageing population, characterised by one of the longest life expectancies and the lowest fertility rate in the world, is likely to drive long-term care (LTC) expenditure higher. This study aims to identify key cost drivers and derive quantitative estimates of Hong Kong's LTC expenditure to 2036. METHODS: We parameterised a macro actuarial simulation with data from official demographic projections, Thematic Household Survey 2004, Hong Kong's Domestic Health Accounts and other routine data from relevant government departments, Hospital Authority and other LTC service providers. Base case results were tested against a wide range of sensitivity assumptions. RESULTS: Total projected LTC expenditure as a proportion of GDP reflected secular trends in the elderly dependency ratio, showing a shallow dip between 2004 and 2011, but thereafter yielding a monotonic rise to reach 3.0% by 2036. Demographic changes would have a larger impact than changes in unit costs on overall spending. Different sensitivity scenarios resulted in a wide range of spending estimates from 2.2% to 4.9% of GDP. The availability of informal care and the setting of formal care as well as associated unit costs were important drivers of expenditure. CONCLUSION: The "demographic window" between the present and 2011 is critical in developing policies to cope with the anticipated burgeoning LTC burden, in concert with the related issues of health care financing and retirement planning.

Educational inequality in physician-diagnosed hypertension widened and persisted among women from 1999 to 2014 in Hong Kong.

Gender differences in the trend of educational inequality in hypertension have been observed especially in the Asian populations, indicating the increasing importance of education as a social determinant of hypertension among women. This study examined the gender-specific trends of educational inequality in physician-diagnosed hypertension in Hong Kong between 1999 and 2014. Based on a series of eight government-led territory-wide household surveys conducted between 1999 and 2014, 97,481 community-dwelling Hong Kong Chinese adults aged 45 or above were analysed. The extent and trend of gender-specific educational inequality in self-reported physician-diagnosed hypertension were estimated by regression-based Relative Index of Inequality and age-standardised Slope Index of Inequality. Over the study period, age-standardised prevalence of self-reported hypertension increased in both genders, with the greatest prevalence among the least educated women. Educational inequalities in hypertension significantly widened in female from 1999 to 2009 and persisted thereafter; nonetheless, the respective inequality was negligible in male. Further adjustment for household income did not attenuate the observed inequality. To conclude, a widened and then persistent discrepancy in hypertension across education levels was observed among women, but not among men, in Hong Kong. The gender perspective should be carefully considered when designing hypertension prevention strategies and related health policies.
