Abstract

OBJECTIVE

Diet and physical activity modifications are prescribed to women with polycystic ovary syndrome (PCOS). This study aimed to evaluate the correlation between physical activity and nutrition-related knowledge, attitudes and practices with obesity indices in young women with PCOS.

DESIGN

A cross-sectional study.

SETTING

Universities located in Shiraz.

PARTICIPANTS

308 young college women (age: 21.51±0.82 years, body mass index (BMI): 23.78±4.36 kg/m) with PCOS who studied in several universities in Shiraz from February to August 2023 participated in the study voluntarily.

METHODOLOGY

Participants filled out a modified Wellness Knowledge, Attitude and Behaviour Instrument, performed the step test to measure their maximum rate of oxygen consumption (VO2max), and their weight, height and waist circumference were measured to estimate their BMI and waist-to-height ratio (WHtR). Pearson product moment correlation and linear regression tests were used for data analysis.

RESULTS

No significant correlation was found between physical activity knowledge and both attitudes (r=0.014, p=0.804) and practices (r=0.49, p=0.399). However, a significant correlation was observed between physical activity attitudes and practices (r=0.125, p=0.028). In terms of nutrition, there were significant weak correlations between nutrition knowledge and attitude (r=0.228, p<0.001) as well as moderate correlations between nutrition attitude and practices (r=0.456, p<0.001), while no significant correlation was found between nutrition knowledge and practices (r=0.093, p=0.102). Additionally, significant negative weak correlations were noted between WHtR and VO2max (r=-0.178, p=0.003), and between BMI and VO2max (r=-0.211, p<0.001), while regression analysis indicated that VO2max is a stronger predictor of WHtR than physical activity practices and significantly predicts BMI.

CONCLUSION

Nutrition and physical activity knowledge were not correlated with practices, while attitude was positively correlated with practices. VO2max demonstrated a stronger association with obesity indices compared with physical activity practices, although further research is warranted to confirm these findings.

摘要

目的

对多囊卵巢综合征（PCOS）女性患者开具饮食和体育活动调整建议。本研究旨在评估PCOS年轻女性的体育活动与营养相关知识、态度和行为与肥胖指数之间的相关性。

设计

横断面研究。

地点

设拉子的大学。

参与者

2023年2月至8月在设拉子几所大学就读的308名患有PCOS的年轻女大学生（年龄：21.51±0.82岁，体重指数（BMI）：23.78±4.36kg/m²）自愿参与本研究。

方法

参与者填写一份经过修改的健康知识、态度和行为量表，进行台阶试验以测量其最大耗氧率（VO₂max），并测量其体重、身高和腰围以估算BMI和腰高比（WHtR）。采用Pearson积矩相关和线性回归检验进行数据分析。

结果

体育活动知识与态度（r = 0.014，p = 0.804）和行为（r = 0.49，p = 0.399）之间均未发现显著相关性。然而，体育活动态度与行为之间存在显著相关性（r = 0.125，p = 0.028）。在营养方面，营养知识与态度之间存在显著弱相关性（r = 0.228，p < 0.001），营养态度与行为之间存在中度相关性（r = 0.456，p < 0.001），而营养知识与行为之间未发现显著相关性（r = 0.093，p = 0.102）。此外，WHtR与VO₂max之间（r = -0.178，p = 0.003）以及BMI与VO₂max之间（r = -0.211，p < 0.001）均存在显著负弱相关性，而回归分析表明，VO₂max比体育活动行为更能预测WHtR，且能显著预测BMI。
