Abstract：
Purpose: To examine the social network factors associated with changes in nutrition risk scores, measured by SCREEN-8, over three years, in community-dwelling Canadians aged 45 years and older, using data from the Canadian Longitudinal Study on Aging (CLSA).Methods: Change in SCREEN-8 scores between the baseline and first follow-up waves of the CLSA was calculated by subtracting SCREEN-8 scores at follow-up from baseline scores. Multivariable linear regression was used to examine the factors associated with change in SCREEN-8 score.Results: The mean SCREEN-8 score at baseline was 38.7 (SD = 6.4), and the mean SCREEN-8 score at follow-up was 37.9 (SD = 6.6). The mean change in SCREEN-8 score was -0.90 (SD = 5.99). Higher levels of social participation (participation in community activities) were associated with increases in SCREEN-8 scores between baseline and follow-up, three years later.Conclusions: Dietitians should be aware that individuals with low levels of social participation may be at risk for having their nutritional status decrease over time and consideration should be given to screening them proactively for nutrition risk. Dietitians can develop and support programs aimed at combining food with social participation.
摘要：
目的：研究与营养风险评分变化相关的社会网络因素，用SCREEN-8衡量，超过三年，居住在社区的45岁及以上的加拿大人，使用加拿大老龄化纵向研究（CLSA）的数据。方法：通过从基线评分中减去随访时的SCREEN-8评分，计算CLSA基线与首次随访波之间SCREEN-8评分的变化。采用多变量线性回归分析SCREEN-8评分变化的相关因素。结果：基线时的平均SCREEN-8评分为38.7（SD=6.4），随访时平均SCREEN-8评分为37.9分(SD=6.6)。SCREEN-8评分的平均变化为-0.90(SD=5.99)。更高水平的社会参与（参与社区活动）与基线和随访之间SCREEN-8分数的增加有关。三年后.结论：营养师应该意识到，社会参与水平低的人可能会面临营养状况随着时间的推移而下降的风险，因此应考虑对他们进行积极的营养风险筛查。营养师可以制定和支持旨在将食物与社会参与相结合的计划。
