Background and Objectives: Several studies have suggested that abnormal levels of serum cholesterol may be a major risk factor for osteoarthritis. However, no studies have been conducted to prevent osteoarthritis under controlled conditions of serum cholesterol. This study aimed to examine the relationship of sociodemographic and anthropometric characteristics, and nutrient and food intakes with osteoarthritis prevalence in Korean elderly subjects with controlled dyslipidaemia. Methods and Study Design: This study included 314 subjects aged ≥65 years who were diagnosed and treated for dyslipidaemia (data from the Seventh Korea National Health and Nutrition Examination Survey, 2016). Among them, 108 were also diagnosed with osteoarthritis. Sociodemographic, health, and nutritional data were analysed. Results: Osteoarthritis prevalence was higher in females, higher-educated subjects, unmarried subjects, non-smokers, and subjects with high body mass index (p＜0.05). After adjusting for the multiple variables, the non-osteoarthritis group had significantly higher vitamin C intake (132±11.0 vs 93.1±11.1 mg/day), fish intake (172±30.0 vs 79.0±12.9 g/day), and seaweed intake (93.7±19.3 vs 38.3±13.4 mg/day) than the osteoarthritis group. Furthermore, the lowest vitamin C, fish, seaweed intake group (quartile 1) each had 3.20, 2.76, 9.93 times higher risk of osteoarthritis than the highest vitamin C, fish, seaweed intake group (quartile 4) (p＜0.05). Conclusions: Among Korean elderly subjects with controlled dyslipidaemia, those with osteoarthritis had lower vitamin C, fish, seaweed intakes than those without osteoarthritis. Although our results do not prove that low vitamin C, fish, seaweed intakes cause osteoarthritis, such relationship is worth exploring for a preventive perspective.

Background and Objectives: Excessive salt intake is a major public health problem in several countries, especially in China. However, few people are aware of their salt intake. The purpose of this study is to carry out salt intake test in routine physical examination, and to explore the salt intake of different populations and their correlation with diet. Methods and Study Design: Spot urine sample was collected to test urinary sodium and create-nine excretions for each participant recruited from physical examinations at the Third Xiangya Hospital. The Tanaka formula was used to estimate 24-h urinary sodium excretion, which reflects salt intake. In addition to physical and laboratory examination, information including personal details, health-related habits, and self-reported disease histories was obtained from the National Physical Examination Questionnaire. Results: In total, 26,406 people completed the salt intake evaluation. After data cleansing, the average salt intake was 8.39±1.80 g/d. Male, middle-aged, overweight and obese, hypertensive, and dyslipidaemic populations, as well as those with non-cardiovascular diseases were more likely to have excessive salt intake. Dietary sources had an effect on salt intake. Salt intake was lower in those who consumed more milk and fruit (both p and p trend＜0.01) but was higher in those who consumed more lean meat (both p and p trend＜0.05), fatty meat (both p and p trend＜0.01) and animal organs (both p and p trend＜0.01). Conclusions: The salt intake in this population far surpasses the recommended amount. We strongly recommend salt intake assessment as routine test into physical examination center.

Background and Objectives: The aim of this study was to determine the associations of dietary diversity with prevalences of allergic diseases. Methods and Study Design: The participants were 1,317 men and women aged 20 to 63 years who were living in Tokushima Prefecture, Japan during the period 2012-2013. We obtained anthropometric data and information on lifestyle characteristics and current medical histories of allergic diseases using a self-administered questionnaire. Dietary intake was assessed using a food frequency questionnaire, and dietary diversity was determined using the Quantitative Index for Dietary Diversity (QUANTIDD). The ORs and 95% CIs for each of the allergic diseases with a 1 standard deviation (SD) increase in the QUANTIDD score were estimated, controlling for age, family history of allergic diseases, education, smoking, drinking, physical activity, energy intake and BMI. Results: Higher dietary diversity showed significant inverse dose-response relationships with allergic diseases and allergic rhinitis in women. Multivariate-adjusted ORs (95% CI) for allergic diseases and allergic rhinitis with 1 SD increase in the QUANTIDD score were 0.77 (95% CI: 0.60-0.98, p=0.037) and 0.69 (95% CI: 0.53-0.90, p=0.007), respectively, in women. There were no significant associations between dietary diversity and allergic diseases in men. Conclusions: The results indicate that there is an inverse association between higher dietary diversity and allergic rhinitis in Japanese female workers.

Background and Objectives: Previous studies on the importance of metabolic syndrome (MS) as a cardiovascular risk factor had not focused on older Chinese adults. The present study analyzed the association of MS with carotid atherosclerosis and the risk of cardiovascular events in Chinese adults. Methods and Study Design: Data of a representative cohort study with 5-year follow-up were used. Community-dwelling people (n=1257) aged ≥55 years without cardiovascular disease (CVD) at baseline were followed up from 2009 to 2014. MS was defined based on the Chinese Diabetes Society criteria under the Chinese Medical Association. Multiple regression analyses were performed to examine the associations of MS with atherosclerosis and CVD events, with adjustment for confounding factors. Results: In a multivariate logistic regression model with adjustment, MS was closely related to common carotid artery intima-media thickness (CCA-IMT) (1.62; 95% CI: 1.19-2.21) and carotid plaque presence (1.38; 95% CI: 1.01-1.89), but not with carotid artery stenosis. At the end of the 5-year follow-up, compared with subjects without MS, hazard ratios and 95% confidence intervals for the different risks in subjects with MS were 1.86 (1.02-3.29) for myocardial infarction (MI), 1.39 (1.01-2.05) for stroke, 1.52 (1.02-2.37) for CVD death, and 1.13 (0.62-2.58) for total death, after adjusting for age, gender, smoking, drinking, physical activity, uric acid, high-sensitivity C-reactive protein, dietary factors and carotid atherosclerosis status. Conclusions: MS was significantly associated with IMT and the presence of carotid plaque and with positively increased risks of MI, stroke, and CVD mortality independent of CVD risk factors in older Chinese adults.

Background and Objectives: Hyperhomocysteinaemia (HHcy) is an independent risk factors for several disorders, including cardiovascular disease. The understanding of the relationship among genetic, epigenetic and the efficacy of folate therapy for HHcy remain unclear. This study aim to investigate whether betaine-homocysteine methyltransferase (BHMT) single-nucleotide polymorphisms (SNPs) and DNA methylation are related to the efficacy of folate therapy for HHcy and whether BHMT DNA methylation mediates the SNP-folate therapy efficacy association. Methods and Study Design: A total of 638 patients with HHcy were involved in this prospective cohort study. Logistic and linear regression was used to explore associations among SNPs, DNA methylation, and folate therapy efficacy. Finally, mediation analysis was performed to investigate whether DNA methylation of BHMT mediates the association between SNPs and folate therapy efficacy. Results: BHMT rs3733890 was significantly associated with folate therapy efficacy (p＜0.05). BHMT and BHMT_1 DNA methylation level was significantly associated with folate therapy efficacy (p=0.017 and p=0.028). DNA methylation of BHMT and BHMT_1 mediated 34.84% and 33.06% of the effect of rs3733890 on folate therapy efficacy, respectively. Conclusions: There has a consistent interrelationship among BHMT genetic variants, methylation levels of BHMT, and folate therapy efficacy. BHMT and BHMT_1 DNA methylation proportionally mediated the effects of rs3733890 SNPs on the efficacy of folate therapy for HHcy.
