Lesbian and bisexual (LB) women have higher body weight than heterosexual women. Interventions focused on health and well-being versus weight loss may be more likely to succeed among LB women. This article describes effects of Women's Health and Mindfulness, a 12-week pilot intervention addressing mindfulness, healthy eating, and physical activity, on outcomes associated with chronic disease risk among overweight and obese LB women older than 40 years.
Eighty women were randomized, using a stepped-wedge design, to either an immediate- or a delayed-start intervention group; the delayed-start group served as the control. Eligible participants were aged 40 years or older, identified as LB, and had a body mass index of 27 or greater. We compared differences in biological markers of chronic disease, mindfulness, nutrition, and physical activity between immediate- and delayed-start intervention groups.
We observed clinically significant improvements in low-density lipoprotein cholesterol but no change in hemoglobin A1c. We found evidence of intervention effects on improved mindfulness and mindful eating scores and on nutrition (improved vegetable intake).
The Women's Health and Mindfulness pilot intervention appears to have initiated positive behavioral and physical health changes in this population. Refinements to the intervention model, such as extended intervention duration, and longer term follow-up are warranted to determine sustained effects.
女同性恋和双性恋（LB）女性的体重高于异性恋女性。针对健康和幸福而非减肥的干预措施在LB女性中可能更有可能取得成功。本文描述了一项为期12周的试点干预项目“女性健康与正念”对40岁以上超重和肥胖LB女性慢性病风险相关结局的影响，该干预项目涉及正念、健康饮食和体育活动。
采用阶梯楔形设计将80名女性随机分为立即开始干预组或延迟开始干预组；延迟开始组作为对照组。符合条件的参与者年龄在40岁及以上，被认定为LB女性，体重指数为27或更高。我们比较了立即开始干预组和延迟开始干预组在慢性病生物标志物、正念、营养和体育活动方面的差异。
我们观察到低密度脂蛋白胆固醇有临床显著改善，但糖化血红蛋白没有变化。我们发现有证据表明干预对改善正念和正念饮食得分以及营养（增加蔬菜摄入量）有效果。
“女性健康与正念”试点干预似乎已在该人群中引发了积极的行为和身体健康变化。有必要对干预模式进行完善，如延长干预持续时间和进行更长期的随访，以确定持续效果。
