Patterns and trends of alcohol consumption in rural and urban areas of China: findings from the China Kadoorie Biobank.

ABSTRACT:

Background

In China, alcohol consumption has increased significantly in recent decades. Little evidence exists, however, about temporal trends in levels and patterns of alcohol consumption and associated factors in adult populations.

Methods

In 2004-08, the China Kadoorie Biobank recruited ~?512,000 adults (41% men, mean age 52?years [SD 10.7]) from 10 (5 urban, 5 rural) geographically diverse regions across China, with ~?25,000 randomly selected participants resurveyed in 2013-14. The self-reported prevalence and patterns (e.g., amount, beverage type, heavy drinking episodes) of alcohol drinking at baseline and resurvey were compared and related to socio-demographic, health and other factors.

Results

At baseline, 33% of men drank alcohol at least weekly (i.e., current regular), compared to only 2% of women. In men, current regular drinking was more common in urban (38%) than in rural (29%) areas at baseline. Among men, the proportion of current regular drinkers slightly decreased at resurvey (33% baseline vs. 29% resurvey), while the proportion of ex-regular drinkers slightly increased (4% vs. 6%), particularly among older men, with more than half of ex-regular drinkers stopping for health reasons. Among current regular drinkers, the proportion engaging in heavy episodic drinking (i.e., >?60?g/session) increased (30% baseline vs. 35% resurvey) in both rural (29% vs. 33%) and urban (31% vs. 36%) areas, particularly among younger men born in the 1970s (41% vs. 47%). Alcohol intake involved primarily spirits, at both baseline and resurvey. Those engaging in heavy drinking episodes tended to have multiple other health-related risk factors (e.g., regular smoking, low fruit intake, low physical activity and hypertension).

Conclusions

Among Chinese men, the proportion of drinkers engaging in harmful drinking behaviours increased in the past decade, particularly among younger men. Harmful drinking patterns tended to cluster with other unhealthy lifestyles and health-related risk factors.

Project description:Background:Higher fruit consumption is associated with lower risk of cardiovascular disease (CVD). Substantial uncertainties remain, however, about the associations of fruit consumption with all-cause mortality and mortality from subtypes of CVD and major non-vascular diseases, especially in China. Methods:In 2004-08, the nationwide China Kadoorie Biobank Study recruited > 0.5 million adults aged 30-79 years from 10 diverse localities in China. Fresh fruit consumption was estimated using an interviewer-administered electronic questionnaire, and mortality data were collected from death registries. Among the 462?342 participants who were free of major chronic diseases at baseline, 17?894 deaths were recorded during ? 7 years of follow-up. Cox regression yielded adjusted rate ratios (RRs) for all-cause and cause-specific mortality associated with fruit consumption. Results:At baseline, 28% of participants reported consuming fruit ??4 days/week (regular consumers) and 6% reported never/rarely consuming fruit (non-consumers). Compared with non-consumers, regular consumers had 27% [RR?=?0.73, 95% confidence interval (CI) 0.70-0.76] lower all-cause mortality, 34% lower CVD mortality (n?=?6166; RR?=?0.66, 0.61-0.71), 17% lower cancer mortality (n?=?6796; RR?=?0.83, 0.78-0.89) and 42% lower mortality from chronic obstructive pulmonary disease (COPD) (n?=?1119; RR?=?0.58, 0.47-0.71). For each of the above, there was an approximately log-linear dose-response relationship with amount consumed. For mortality from site-specific cancers, fruit consumption was inversely associated with digestive tract cancer (n?=?2265; RR?=?0.72, 0.64-0.81), particularly oesophageal cancer (n?=?801; RR?=?0.65, 0.50-0.83), but not with cancer of lung or liver. Conclusions:Among Chinese adults, higher fresh fruit consumption was associated with significantly lower mortality from several major vascular and non-vascular diseases. Given the current low population level of fruit consumption, substantial health benefits could be gained from increased fruit consumption in China.

Project description:AimsTo assess the associations of problem drinking with wellbeing and mortality in Chinese men.DesignPopulation-based prospective cohort study.SettingTen diverse areas across China.ParticipantsA total of 210 259 men aged 30-79 years enrolled into China Kadoorie Biobank between 2004 and 2008.MeasurementsSelf-reported alcohol intake and indicators of problem drinking (i.e. drinking in the morning, unable to stop drinking, unable to work due to drinking, negative emotions after drinking, having shakes after stopping drinking) were assessed by questionnaire at baseline, along with stressful life events (e.g. divorce, income loss, violence) and wellbeing-related measures (e.g. life satisfaction, sleep problems, depression, anxiety). Problem drinking was defined as reporting at least one of the drinking problem indicators. Follow-up for mortality and hospitalized events was through linkage to death registries and national health insurance systems. Multivariate logistic regression models assessed cross-sectional relationships between problem drinking and stressful life events/wellbeing. Cox proportional hazards regression models estimated prospective associations of problem drinking with mortality/hospitalized events.FindingsA third of men were current regular drinkers (i.e. drank alcohol at least weekly), 24% of whom reported problem drinking: 8% of all men. Experience of stressful life events in the past 2 years, especially income loss [odds ratio (OR) = 1.86, 95% confidence interval (CI) = 1.45-2.39], was associated with increased problem drinking. Compared with low-risk drinkers (i.e. intake < 200 g/week, no reported problem drinking or habitual heavy drinking episodes), men with problem drinking had poorer self-reported health, poorer life satisfaction and sleep problems, and were more likely to have symptoms of depression and anxiety. Men with two or more problem drinking indicators had an approximately twofold higher risk for all-cause mortality as well as mortality and morbidity from external causes (i.e. injuries), respectively, and 15% higher risk for any hospitalization, compared with low-risk drinkers (all P < 0.01).ConclusionEight per cent of men in China are problem drinkers, and this is associated with significantly increased risk of physical and mental health problems and premature death.
