Do health-related knowledge, beliefs and self-efficacy differ between women with and without polycystic ovary syndrome (PCOS)?
Women with PCOS felt at greater risk for adverse health outcomes, yet believed a healthy lifestyle was less beneficial to prevent weight gain relative to a comparison group.
Diet and physical activity are often used to treat PCOS, but there are high attrition rates and less engagement in self-help methods. It is unclear whether there are unique psychosocial considerations in PCOS that should be incorporated into these interventions.
STUDY DESIGN, SIZE, DURATION: This cross-sectional study enrolled 475 women with (N = 255) and without PCOS (N = 220).
PARTICIPANTS/MATERIALS, SETTING, METHODS: Female participants were recruited through paper and web-based advertisements across the US (mean age: 28.1 ± 5.4 years). Participants were either diagnosed with PCOS by a healthcare professional (PCOS group) or had self-reported regular menstrual cycles (comparison group). A reliable and valid online instrument about health-related knowledge, beliefs and self-efficacy was administered to these participants.
Most women with PCOS had a basic understanding of nutrition (96%), but had misconceptions about diagnostic criteria for PCOS (≥86%). PCOS was associated with greater perceived susceptibility for disease and weight gain and poorer perceived control over these health outcomes (all P < 0.05), in relation to the comparison group. Women with PCOS also perceived fewer benefits of healthy behaviors on weight gain (P = 0.03) with less than half of the PCOS group attempting to follow government diet recommendations (47%). There were no differences in the self-efficacy of dietary behaviors between groups.
LIMITATIONS, REASONS FOR CAUTION: It is likely that participant self-selection occurred due to the nature of recruitment in this study and results may have limited generalizability since most participants identified as Caucasian. Additionally, it is unclear whether some results may be clinically meaningful due to small effect sizes.
These findings support that behavioral interventions should incorporate the unique psychosocial considerations associated with PCOS to encourage patient participation in lifestyle interventions.

多囊卵巢综合征(PCOS)患者与非 PCOS 患者的健康相关知识、信念和自我效能感是否存在差异?
与对照组相比,PCOS 患者认为自己面临更大的健康问题风险,但她们认为健康的生活方式对预防体重增加的益处较小。
饮食和体育锻炼常用于治疗 PCOS,但治疗效果往往不尽人意,且患者参与自我帮助方法的意愿较低。目前尚不清楚 PCOS 是否存在独特的社会心理考虑因素,这些因素应纳入这些干预措施中。
研究设计、规模和持续时间:这项横断面研究纳入了美国各地通过纸质和网络广告招募的 475 名女性参与者(PCOS 组 255 名,非 PCOS 组 220 名)。
参与者/材料、设置、方法:通过可靠有效的在线健康相关知识、信念和自我效能感问卷评估女性参与者的健康状况。
大多数 PCOS 患者对营养有基本的了解(96%),但对 PCOS 的诊断标准存在误解(≥86%)。与对照组相比,PCOS 患者对疾病和体重增加的易感性更高,对这些健康结果的控制能力更差(均 P < 0.05)。PCOS 患者也认为健康行为对体重增加的益处较小(P = 0.03),只有不到一半的 PCOS 组尝试遵循政府的饮食建议(47%)。两组在饮食行为自我效能方面没有差异。
局限性、谨慎原因:由于本研究的招募性质,参与者可能存在自我选择,且由于大多数参与者为白种人,研究结果可能具有一定局限性。此外,由于效应量较小,一些结果是否具有临床意义尚不清楚。
这些发现支持行为干预措施应纳入与 PCOS 相关的独特社会心理因素,以鼓励患者参与生活方式干预。
