AimWe旨在澄清是否吃零食的习惯降低全因死亡的风险在日本老年population.MethodsThe研究参与者是64或65岁的社区居民招募每个调查年从1996年到2005年。在基线调查期间，使用自填问卷获得了关于零食频率和其他生活方式因素的数据，并每年对参与者进行随访，直到2017年底。共有2943名参与者（1484名男性和1459名女性）符合条件。全因死亡率进行了比较，参与者分组的频率吃零食（没有吃零食，1至4次/周，或每天）。ResultsThe死亡人数记录在研究期间的43 204人年为357（24.1%）男性和173（11.9%）女性。随访期的平均值±标准差为男性14.2 ± 4.9年，女性15.2 ± 4.5年。考克斯比例风险回归分析显示，在调整潜在的混杂因素后，女性的风险比为0.64（95%置信区间[CI]，0.43-0.94）在有每周吃1 - 4次零食习惯的组中，每天吃零食组与不吃零食组比较，差异有统计学意义（P <0.05），差异有统计学意义（P <0.05）。这些协会中没有观察到男性。ConclusionsA中等频率的零食略有降低风险的全因死亡率的妇女。我们的发现可能有助于改善老年女性的营养状况。Geriatr Gerontol Int 2021; 21：697-704。
AimWe aimed to clarify whether snacking habits decrease the risk of all‐cause mortality in an older Japanese population.MethodsThe study participants were 64‐ or 65‐year‐old community‐dwelling residents recruited each survey year from 1996 through 2005. Data on the frequency of snacking and other lifestyle factors were obtained during the baseline survey using self‐administered questionnaires, and the participants were followed up annually until the end of 2017. In total, 2943 participants (1484 men and 1459 women) were eligible. All‐cause mortality was compared among participants grouped by frequency of snacking (no snacking, one to four times/week, or every day).ResultsThe number of deaths recorded over the study period of 43 204 person‐years was 357 (24.1%) for men and 173 (11.9%) for women. The mean ± standard deviations for the follow‐up period were 14.2 ± 4.9 years in men and 15.2 ± 4.5 years in women. Cox proportional hazard regression analyses showed that after adjusting for potential confounding factors, the hazard ratios for women were 0.64 (95% confidence interval [CI], 0.43–0.94) in the group that had a habit of snacking one to four times/week, and 0.93 (95% CI 0.63–1.36) in the group that had a habit of snacking every day compared with those in the no snacking group. These associations were not observed among men.ConclusionsA moderate frequency of snacking slightly decreases the risk of all‐cause mortality among women. Our findings might be useful for improving the nutrition statuses in older female adults.Geriatr Gerontol Int 2021; 21: 697–704.
