Lifestyle characteristics and 3-year total mortality of Japanese with self-reported diabetes.

摘要

Despite the significant adverse health consequences of diabetes, data on lifestyle characteristics and mortality among the Japanese with diabetes are limited. Our objective was to investigate the lifestyles of Japanese community residents with self-reported diabetes and their 3-year total mortality. Our cohort was 7178 randomly selected residents aged 30-79 years in Nihonmatsu City, Fukushima Prefecture, Japan; 5187 responded to the survey (72% response rate) and were followed for 3 years. Baseline data were collected using questionnaires in December 2002, and deaths were monitored monthly. Only 19% of women and 4% of men followed six to seven of Breslow's seven health practices. The percentage of people with self-reported diabetes was 4.2%[95% confidence interval (CI), 3.4-5.1%] for women and 7.9% (95% CI, 6.8-9.1%) for men, and the 3-year total mortality was 1.4% (95% CI, 1.0-1.9%) for women and 3.1% (95% CI, 2.4-3.8%) for men. Factors associated with 3-year mortality were fair or poor subjective health [odds ratio (OR) = 3.1, 95% CI 1.7-5.5] and self-reported diabetes (OR = 2.3, 95% CI 1.1-4.9) in a logistic regression controlling for age and gender. In stratified analyses, 3-year mortality of those with diabetes was significantly higher than those without the disease among men and those aged under 65. Those with diabetes were more likely to have self-reported comorbidities, high blood pressure and report poor subjective health regardless of age and gender, and healthier lifestyles among the women and those aged under 65. Our results support the need for community-based primary prevention measures to improve the lifestyles of residents, along with secondary prevention approaches to monitor those with diabetes for complications and to give them lifestyle instructions.
