RESUMEN
Several studies have reported a J-shaped relationship between alcohol consumption and coronary heart disease (CHD) risk. However, the mechanisms of this relationship remain unclear. This study aimed to evaluate the relationships of alcohol consumption with established CHD risk factors and with macro-/micro-nutrient intake among Japanese people. Participants were 1,090 Japanese men and women aged 40-59 y enrolled in the INTERLIPID study, excluding former drinkers. Based on two 7-d alcohol records, participants were classified as non-drinkers (0 g/wk), light-drinkers (<100 g/wk), moderate-drinkers (100-299 g/wk), or heavy-drinkers (≥300 g/wk). Detailed macro-/micro-nutrient intake was evaluated using four in-depth 24-h dietary recalls and adjusted for total energy intake excluding alcohol. We analyzed the associations of CHD risk factors and nutrient intake with alcohol consumption. Serum high-density lipoprotein cholesterol and blood pressure were higher and low-density lipoprotein cholesterol was lower among those with higher alcohol consumption. J-shaped relationships with alcohol consumption were observed for the proportion of current smokers, number of cigarettes smoked, and prevalence of hypertension; these risk factors were lowest among light-drinkers. Carbohydrate and total fiber intakes were lower and protein and dietary cholesterol intakes were higher among those with higher alcohol consumption. These associations were similar for men and women. Alcohol consumption was related to nutrient intake as well as established CHD risk factors. Non-drinkers were higher on some CHD risk factors than were light-drinkers. These findings may influence the J-shaped relationship between alcohol consumption and CHD risk.

The consumption of red meat has been recommended for individuals with reduced kidney function. However, red meat intake was recently suspected to increase cardiovascular disease (CVD) risk. We evaluated the association of red meat intake with CVD mortality risk in Japanese with/without reduced kidney function. Overall, 9112 participants of a Japanese national survey in 1980, aged ≥30 years, were followed for 29 years. Red meat intake was assessed using weighed dietary record. Cox proportional hazards models were used to estimate the hazard ratio (HR) of CVD mortality according to sex-specific tertiles of red meat intake. We also performed stratified analyses with/without reduced kidney function defined as estimated glomerular filtration rate less than 60 mL/min/1.73 m2. Red meat intake was not associated with CVD mortality risk in men and women. In stratified analyses, the HR of the highest compared with the lowest tertile of red meat intake was lower only in women with reduced kidney function (0.67, 95% confidence interval 0.46-0.98). In conclusion, there were no clear associations between red meat intake and CVD mortality risk in Japanese population; however, a higher intake of red meat was associated with lower risk of future CVD mortality in women with reduced kidney function.

Although heavy alcohol consumption has been identified as a risk factor for adverse cognitive functioning, it currently remains unclear whether moderate alcohol consumption exerts similar effects. Observational studies previously reported the potential benefits of moderate alcohol consumption on cognition, particularly in the elderly; however, these effects have not yet been demonstrated in Asian populations. The aim of the present study was to investigate the relationship between alcohol consumption levels and global and domain-specific cognitive functions in cognitively intact elderly Japanese men. Cross-sectional data from the Shiga Epidemiological Study of Subclinical Atherosclerosis (SESSA), an ongoing prospective, population-based study in Shiga, Japan, were used to examine the relationship between alcohol consumption and cognitive function. Men (n = 585) aged ≥65 years provided information on their weekly consumption of alcohol, and the data obtained were used to construct categories of never, ex- (quit before interview), very light (<14 g/day), light (14-23 g/day), moderate (>23-46 g/day), and heavy (>46 g/day) drinkers. Cognitive function was measured using the Cognitive Abilities Screening Instrument (CASI). A fractional logistic regression model adjusted for age, education, body mass index, smoking, exercise, hypertension, diabetes, and dyslipidemia showed that the CASI scores for global and domain-specific cognitive functions were not significantly different between all subgroups of current drinkers and never-drinkers. However, the CASI score of ex-drinkers (multivariable adjusted mean CASI score [SD]) was significantly lower than that of never-drinkers in the global [never vs. ex: 90.16 (2.21) vs. 88.26 (2.58)] and abstraction and judgment domain [never vs. ex: 9.48 (0.46) vs. 8.61 (0.57)]). The present results do not suggest any beneficial or adverse relationship between current alcohol consumption levels and cognitive functioning (both global and domain specific) in elderly Japanese men; however, low cognitive function among ex-drinkers warrants future investigations to identify the factors causing drinkers to quit.
