Hong Kong has been one of the fastest growing postwar economies with substantial decline in mortality risks during the past decades. Nevertheless, it is unclear whether there is a socioeconomic ...disparity in the trends of mortality risks across generations.
We conducted a series of sex-specific age-period-cohort analyses by neighborhood-level socioeconomic status (SES) using mortality data from 1976 to 2010 to examine the socioeconomic disparity of cohort effects. Outcomes included all-cause mortality and mortality from ischemic heart disease, other cardiovascular diseases (CVD), lung cancer, other cancers, respiratory diseases (RD), other medical causes, and external causes.
Age-standardized mortality rates declined in both sexes, with generally higher rates observed in those of lower SES. Socioeconomic disparity in the risks of all mortality outcomes emerged and widened starting from cohorts born around the 1930s-1940s. These results suggested that mortality risks associated with lower SES did not decline across generations as much as those associated with higher SES.
The share of health benefits brought by economic growth was notably unequal by SES with greater benefits for those of higher SES. More attention should be paid to postwar baby boomers of lower SES.
•Age-standardized mortality was generally higher in those of lower socioeconomic status (SES) and declined in both sexes.•Greater mortality risks for people of lower SES emerged because of the cohorts born in 1930s-1940s.•Socioeconomic disparity of mortality risks continued to widen till recent cohorts.•The changes of mortality risks coincided with one of the fastest postwar economic developments.•Health benefits brought by rapid economic development were greater for people of higher SES.
Previous research has suggested a differential short-term effect of multimorbidity on hospitalization by age, with younger groups affected more. This study compares the nine-year hospitalization ...pattern by age and multimorbidity status in a retrospective cohort of discharged in-patients, who represent a high-need portion of the population.
We examined routine clinical records of all patients aged 45+ years with chronic conditions discharged from public general hospitals in 2005 in Hong Kong. Patterns of annual frequencies of hospital admissions and number of hospitalized days over nine years (2005–2014) were compared by multimorbidity status (1, 2, 3+ conditions) and age group (45–64, 65–74, 75+).
Among 121,188 included patients, 33.9% had 2+ conditions and 12.3% had 3+. Hospitalization patterns varied by age and multimorbidity status. For those having only 1 condition, annual number of admissions was similar by age, but older patients had more hospitalized days (4.40 days per person-year for the 45–64 group versus 10.29 for the 75+ group in the 5th year). For those with 3+ conditions, younger patients had more admissions (4.39 admissions per person-year for the 45–64 group versus 1.87 for the 75+ group in the 5th year) but similar number of hospitalized days with older patients. Interaction analysis showed effect of multimorbidity on hospitalization was stronger in younger groups (P < 0.05).
Middle-aged discharged in-patients with multimorbidity are admitted more often than their older counterparts and have similar total hospitalized days per year. Further research is needed to investigate chronic care needs of younger people with multimorbidity.
•Middle-aged multimorbid in-patients were admitted more often than older ones after discharge.•Given similar multimorbidity status, older patients spent more days in hospitals annually.•With three or more conditions, number of hospitalized days did not differ substantially by age.•Adjusted association of multimorbidity with hospitalization was weaker in younger patients.•Middle-aged multimorbid patients represent a vulnerable group with distinct chronic care needs.
A cross-sectional relationship between lower urinary tract symptoms (LUTS) and depressive symptoms was previously reported among Southern Chinese men; however, the temporal relationship was unclear. ...Our objective is to evaluate the temporal relationship between moderate to severe lower urinary tract symptoms and clinically significant depressive symptoms in elderly Chinese men aged 65 in a prospective manner. In a prospective cohort of 2,000 Chinese men aged 65 to 92 years in Hong Kong, we studied the association of having moderate to severe LUTS at baseline and having clinically relevant depressive symptoms at year 2 follow-up. After excluding men with prostate or bladder cancer or surgery (n = 20) and lost to follow-up (n = 254), data on 1,726 subjects were analyzed. LUTS were measured by the International Prostate Symptom score; and clinically relevant depressive symptoms were measured by the Geriatric Depression Scale. The multiple logistic regressions showed that the presence of moderate-to-severe LUTS at baseline were significantly associated with increased risk for being depressed at two-year follow-up, with adjustments for demographic, lifestyle, medical factors, weight status and stressful life events (OR = 2.97; CI: 1.70-5.20). Association remained significant with additional adjustments for baseline GDS score (OR = 1.88; CI: 1.03-3.41). LUTS are important risk factors in predicting the presence of clinically relevant depressive symptoms. In elderly men, increased awareness and possible screening are needed to detect the increased risk of clinically relevant depressive symptoms.
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 (
= 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.
Abstract
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.
Adherence with oral hypoglycaemic agent is crucial to achieve optimal glycaemic control. The 8-item Morisky Medication Adherence Scale (MMAS-8) has been frequently used, yet the association between ...MMAS-8 score and glycaemic control among Chinese diabetes patients is largely unknown. Two general out-patient clinics were randomly selected in a district with socio-demographic characteristics representative of the entire Hong Kong population. A consecutive sample of adult type-2 diabetes patients currently taking oral hypoglycaemic agents was included. The glycaemic control was reflected by the level of hemoglobin A1c (HbA1c) taken within the previous 6 months. Factors associated with poor glycaemic control (HbA1c ≥ 7.0%) were evaluated by linear regression analysis. From 565 eligible Chinese patients with an average age of 63.2 years (SD 9.7) and male proportion of 46.5%, the average HbA1c was 7.1% (SD 1.1%), and 52.0% had poor glycaemic control. The proportion of poor medication adherence (MMAS-8 ≤ 6) was 32.2%. After controlling for socio-demographics, lifestyle, medication use, and health characteristics, the MMAS-8 score was correlated with better glycaemic control (beta -0.095; 95%CI -0.164 to -0.026, P = .007). The MMAS-8 score had a weak and negative correlation with HbA1c level. The instrument should be applied with caution when predicting glycaemic control in clinical practice.
ObjectivesPrevalence of multimorbidity has been increasing worldwide. While population ageing undoubtedly contributes, secular trends have seldom been decomposed into age, period and cohort effects ...to investigate intergenerational differences. This study examines the birth cohort effect on morbidity burden and multimorbidity in Hong Kong community.DesignSex-specific age-period-cohort analysis with repeated cross-sectional surveys.SettingA territory-wide population survey database.Participants69 636 adults aged 35 or above who participated in the surveys in 1999, 2001, 2005 or 2008.Main outcome measuresMorbidity burden was operationalised as number of chronic conditions from a list of 14, while multimorbidity was defined as a dichotomous status of whether participants had two or more conditions.ResultsFor both sexes, there was an upward inflection (positive change) of risk of increased morbidity burden starting from cohort 1955–1959. For men born after 1945–1954, there was a trend of lower risk (relative risk=0.63, 95% CI 0.50 to 0.80 for 1950–1954 vs 1935–1939) which continued through subsequent cohorts but with no further declines. In women, there had been a gradual increase of risk, although only significant for cohort 1970–1974 (relative risk=1.90, 95% CI 1.08 to 1.34 vs 1935–1939). Similar results were found for dichotomous multimorbidity status.ConclusionsThe trend of lower risk starting from men born in 1945–1954 may be due to a persistent decline in smoking rates since the 1980s. On the other hand, the childhood obesity epidemic starting from the late 1950s coincided with the observed upward inflection of risk for both sexes, that is, notably more drastic increase of risk in women and the levelling-off of the decline of risk in men. These findings highlight that the cohort effects on morbidity burden and multimorbidity may be sex-specific and contextual. By examining such effects in different world populations, localised sex-specific and generation-specific risk factors can be identified to inform policy-making.
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.
This study analyzed inequalities in health status among different socioeconomic and demographic rural residents covered by the New Rural Cooperative Medical System in China.
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.
Compared with those with lower education attainment, the respondents with higher education levels tended to report a higher VAS score (β = 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.
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.
This study aimed to give an international perspective of health service gaps for caring for elderly individuals and explore the role of primary care for caring for elderly individuals with chronic ...conditions in Hong Kong.
Cross-sectional, telephone survey.
Hong Kong.
A sample of 1000 Chinese participants in Hong Kong aged 60 or older.
Questionnaire extracted from the Commonwealth Fund 2014 International Health Policy Survey of Older Adults.
Similar to the 11 countries, more than half (about 65%) of Hong Kong respondents suffered from chronic conditions, whereas approximately one-third of them had at least 2 chronic conditions. US respondents had highest rate of having chronic conditions. Only 65% of Hong Kong respondents reported having a regular source of care and a higher proportion of elderly reported having poor self-rated health when compared with overseas counterparts. However, the proportion of elderly individuals who could access same-day or next-day medical care was higher compared with findings of other countries. Both Hong Kong and US respondents were more likely to report cost-related problems when accessing care. Waiting time for specialists in Hong Kong was much longer and coordination between regular doctors was poorer than in all other countries. Although half of Hong Kong respondents had a management plan for chronic conditions, a smaller proportion of them considered it helpful.
Hong Kong has the lowest rate of regular source of care when compared with 11 developed countries, although people in Hong Kong were more likely to be able to access same-day or next-day medical care. To cope with increasing needs of chronic disease care, there may be a need to further develop the provision of regular source of care for elderly individuals, including the development of quality primary care in Hong Kong.
