In-person lifestyle interventions for obesity treatment yield significant improvements in depression. These improvements may be attributed to the excellent weight losses produced by in-person interventions. In contrast, Internet programs yield more modest weight losses, and their effect on depression is unknown. This study is the first to examine whether Internet-delivered obesity treatment impacts depressive symptoms.
Participants (N = 136) were randomized to either a community campaign plus Internet behavioral weight loss (IBWL) or community campaign alone (Control). IBWL did not include online social support components. A measure of depressive symptoms was administered, and weight was objectively assessed.
Of the total sample, 24% met the clinical cutoff for elevated depression risk at baseline. IBWL participants lost more weight during treatment (P = 0.005) and experienced significantly greater improvements in depressive symptoms (P = 0.02). Among participants who met the clinical cutoff for elevated risk for depression at baseline, those assigned to IBWL had greater improvements in depressive symptoms during treatment compared to Control (P = 0.033). Consequently, at post-treatment, a smaller percentage of IBWL participants were at elevated risk for depression.
This study is the first to show that Internet-delivered obesity treatment improves depression risk and depressive symptoms in individuals with overweight or obesity.
面对面的肥胖治疗生活方式干预能显著改善抑郁症状。这些改善可能归因于面对面干预带来的显著体重减轻。相比之下，网络项目带来的体重减轻幅度较小，其对抑郁的影响尚不清楚。本研究首次探讨网络肥胖治疗是否会影响抑郁症状。
参与者（N = 136）被随机分为社区活动加网络行为减肥（IBWL）组或仅参加社区活动的对照组。IBWL不包括在线社交支持部分。对抑郁症状进行测量，并客观评估体重。
在总样本中，24%的人在基线时达到抑郁风险升高的临床临界值。IBWL组参与者在治疗期间体重减轻更多（P = 0.005），抑郁症状改善也更显著（P = 0.02）。在基线时达到抑郁风险升高临床临界值的参与者中，与对照组相比，分配到IBWL组的参与者在治疗期间抑郁症状改善更明显（P = 0.033）。因此，在治疗后，IBWL组中处于抑郁风险升高状态的参与者比例较小。
本研究首次表明，网络肥胖治疗可降低超重或肥胖个体的抑郁风险并改善抑郁症状。
