饮食质量差在老年人中很常见，但人们对食物选择的影响知之甚少，包括心理社会因素在这个年龄段的作用。在59-73岁的男性和女性社区居民中确定饮食质量的心理社会相关因素;描述10年来饮食质量变化的关系。纵向队列，赫特福德郡队列研究（HCS）。在基线时评估了HCS参与者（1998-2001年：1048名男性，862名女性）; 2011年重新评估了183名男性和189名女性。通过食物频率问卷评估饮食;计算饮食评分以描述基线和随访时的饮食质量。采用问卷调查的方法对一系列心理社会因素（社会支持、社会网络、休闲活动参与、抑郁和焦虑、控制感）进行评估。在基线时，更好的饮食质量与一系列社会因素有关，包括增加的信任/情感社会支持（男性和女性），实际支持（男性）和更大的社会网络（女性）（所有p<0.05）。对于男性和女性来说，更多地参与社交和认知休闲活动与更好的饮食质量有关（p<0.005）。在随访亚组中，基线时测量的心理社会因素与10年内饮食评分的变化之间几乎没有关联。然而，对于男性（p=0.017）和女性（p=0.014），在基线时更多地参与休闲活动，特别是认知活动，与10年随访期间饮食质量的下降幅度较小相关。在社区居住的老年人中，一系列社会因素，包括更多地参与休闲活动，与更好的饮食质量有关。
Poor diet quality is common among older people, but little is known about influences on food choice, including the role of psychosocial factors at this age. To identify psychosocial correlates of diet quality in a community-dwelling population of men and women aged 59-73 years; to describe relationships with change in diet quality over 10 years. Longitudinal cohort, Hertfordshire Cohort Study (HCS). HCS participants assessed at baseline (1998-2001: 1048 men, 862 women); 183 men and 189 women re-assessed in 2011. Diet was assessed by administered food frequency questionnaire; diet scores were calculated to describe diet quality at baseline and follow-up. A range of psychosocial factors (social support, social network, participation in leisure activities, depression and anxiety, sense of control) were assessed by questionnaire. At baseline, better diet quality was related to a range of social factors, including increased confiding/emotional social support (men and women), practical support (men), and a larger social network (women) (all p<0.05). For both men and women, greater participation in social and cognitive leisure activities was related to better diet quality (p<0.005). There were few associations between measured psychosocial factors at baseline and change in diet score over 10 years, in the follow-up sub-group. However, greater participation in leisure activities, especially cognitive activities, at baseline was associated with smaller declines in diet quality over the 10-year follow-up period for both men (p=0.017) and women (p=0.014). In community-dwelling older adults, a range of social factors, that includes greater participation in leisure activities, were associated with diets of better quality.
