BACKGROUND
Sufficient physical activity (PA) is important to reduce the risk of men developing chronic diseases and to improve mental health. The effectiveness of PA programmes can vary, however, among men. Individual and socio-psychological characteristics may affect the level of men's PA before starting a behaviour change programme as well as changes in PA during the programme.
AIMS
The primary objective of this study was to examine the role of individual and socio-psychological characteristics in predicting men's (a) accelerometer-assessed PA (step count and moderate to vigorous PA [MVPA]) upon presentation to a behaviour change programme and (b) changes in PA (step count and MVPA) during a behaviour change programme.
METHODS
A total of 109 men (mean age = 45.5 years, = 7.8 years, mean body mass index = 34.5 kg/m, = 5.1 kg/m) who participated in the 3-month PA and dietary behaviour change programme in 2018 participated in this study. Before and after completing the 12-week programme, men completed assessments including individual (age, weight) and socio-psychological (psychological needs support, psychological needs satisfaction, positive affect and negative affect) characteristics. We used regression analysis to examine the relationship between these variables and PA.
RESULTS
At baseline, men's weight (β = -.36, < .001) and positive affect (β = .29, < .01) were significant predictors of step count. At baseline, men's weight (β = -.21, < .05) and negative affect (β = .23, < .05) were significant predictors of MVPA, though the overall model did not display statistical significance. The overall regression models did not significantly predict changes in either step count or MVPA pre- to post-programme.
CONCLUSION
The influence of weight and positive and negative affect in predicting PA outcomes suggests that tailoring men's health behaviour change interventions to individual circumstances and needs could enhance their effectiveness for some men.
背景
充足的身体活动对于降低男性患慢性病的风险以及改善心理健康至关重要。然而，身体活动计划的效果在男性中可能存在差异。个体和社会心理特征可能会影响男性在开始行为改变计划之前的身体活动水平以及计划期间身体活动的变化。
目的
本研究的主要目的是检验个体和社会心理特征在预测男性（a）参加行为改变计划时通过加速度计评估的身体活动（步数和中等到剧烈身体活动[MVPA]）以及（b）行为改变计划期间身体活动（步数和MVPA）变化方面的作用。
方法
共有109名男性（平均年龄 = 45.5岁，标准差 = 7.8岁，平均体重指数 = 34.5 kg/m²，标准差 = 5.1 kg/m²）参与了本研究，他们在2018年参加了为期3个月的身体活动和饮食行为改变计划。在完成为期12周的计划之前和之后，男性完成了包括个体（年龄、体重）和社会心理（心理需求支持、心理需求满足、积极情绪和消极情绪）特征的评估。我们使用回归分析来检验这些变量与身体活动之间的关系。
结果
在基线时，男性的体重（β = -0.36，p < 0.001）和积极情绪（β = 0.29，p < 0.01）是步数的显著预测因素。在基线时，男性的体重（β = -0.21，p < 0.05）和消极情绪（β = 0.23，p < 0.05）是MVPA的显著预测因素，尽管总体模型未显示统计学意义。总体回归模型在计划前到计划后均未显著预测步数或MVPA的变化。
结论
体重以及积极和消极情绪对预测身体活动结果的影响表明，根据男性的个体情况和需求量身定制健康行为改变干预措施可能会提高对某些男性的有效性。
