BACKGROUND
Greater than 60% of adults have overweight or obesity. Self-weighing is an effective weight loss and weight maintenance tool. However, little is known about self-weighing habits among the primary care patient population. Our objective was to examine the frequency of patient-reported self-weighing, and to evaluate the associations of self-weighing with demographic characteristics and self-monitoring behaviors.
METHODS
We conducted an analysis of survey data collected as part of the PaTH Clinical Data Research Network, which recruited a cohort of 1,021 primary care patients at 4 academic medical centers. Patients of all body mass index (BMI) categories were included.
RESULTS
Response rate of 6-month survey was 727 (71%). The mean age was 56 years, and most were female (68%), White (78%), college graduates (66%), and employed/retired (85%). The mean BMI was 30.2 kg/m, 80% of participants had a BMI ≧ 25 kg/m. Of patients with BMI ≧ 25 kg/m, 35% of participants self-weighed weekly and 23% daily. Participants who reported self-weighing at least weekly were more likely to be older (59 vs 54 years, p < 0.01), married (p = 0.01), college graduates (p = 0.03), White (p < 0.01), and employed vs disabled/unemployed (p < 0.01). Patients who self-weighed daily had a lower BMI (29 kg/m vs 31 kg/m, p = 0.04). Patients who tracked exercise or food intake were more likely to self-weigh daily (p < 0.01), as were patients wanting to lose or maintain weight (p < 0.01).
CONCLUSIONS
Despite its potential for primary and secondary obesity prevention, only 35% of primary care patients with overweight or obesity engage in self-weighing weekly and less than a quarter (23%) self-weigh daily. Socioeconomic status appears to be a factor influencing regular self-weighing in this population, potentially contributing to greater health disparities in obesity rates. Patients who self-weighed daily had a lower BMI, suggesting that it may play a role in primary prevention of obesity. More work is needed to explore self-weighing among patients.
背景
超过 60%的成年人超重或肥胖。自我称重是一种有效的减肥和保持体重的工具。然而，对于初级保健患者人群的自我称重习惯知之甚少。我们的目的是检查患者报告的自我称重频率，并评估自我称重与人口统计学特征和自我监测行为的关联。
方法
我们对作为 PaTH 临床数据研究网络一部分收集的调查数据进行了分析，该网络在 4 家学术医疗中心招募了 1021 名初级保健患者。所有体重指数 (BMI) 类别均包括在内。
结果
6 个月调查的回复率为 727 人（71%）。平均年龄为 56 岁，大多数为女性（68%）、白人（78%）、大学毕业（66%）和在职/退休（85%）。平均 BMI 为 30.2kg/m，80%的参与者 BMI≧25kg/m。在 BMI≧25kg/m 的患者中，35%的参与者每周称重一次，23%的参与者每天称重一次。每周至少称重一次的参与者更可能年龄较大（59 岁比 54 岁，p<0.01）、已婚（p=0.01）、大学毕业（p=0.03）、白人（p<0.01）、在职/退休（p<0.01）。每天称重的患者 BMI 较低（29kg/m 比 31kg/m，p=0.04）。每天自我称重的患者更有可能记录运动或饮食摄入（p<0.01），以及想要减肥或保持体重的患者（p<0.01）。
结论
尽管自我称重可能有助于初级和二级肥胖预防，但只有 35%的超重或肥胖的初级保健患者每周进行自我称重，不到四分之一（23%）的患者每天自我称重。社会经济地位似乎是影响该人群定期自我称重的一个因素，这可能导致肥胖率方面的健康差异更大。每天自我称重的患者 BMI 较低，这表明它可能在肥胖的初级预防中发挥作用。需要进一步努力探索患者的自我称重情况。
