Background: Cardiorespiratory fitness (CRF) is one of the most important components of physical fitness. Low levels of CRF are associated with high mortality risk.
Objective: To investigate factors associated with CRF in postmenopausal women with prehypertension.
Methods: A descriptive design was used in this study. Through purposive sampling, 84 postmenopausal women with prehypertension were recruited from Ratchaburi province. The data were collected by using the structured questionnaire with face-to-face interview. All of the participants were measured for CRF (estimated maximal oxygen uptake [VO2max]). Data were analyzed using descriptive and inferential statistics.
Results: The results revealed that mean age of participants was 55.15 ± 7 years (range, 44 - 69 years). Most of them were married (69%), obtained primary education (76.2%), worked as farmer (76.2%), and none farmers (23.8%). Approximately half of them did not exercise (42.9%). CRF was associated with waist circumference
(rp = -0.637, P < 0.001), body mass index (rp = -0.562, P < 0.001), heart rate (rp = -0.581, P < 0.001), and occupation (rs = 0.396, P < 0.001).
Conclusions: Factors including waist circumference, body mass index, and heart rate were negatively associated with CRF in postmenopausal women with prehypertension. The results suggest approaches for healthcare providers to develop programs promoting cardiorespiratory fitness among postmenopausal women with prehypertension to enhance their health status and prevent hypertension and cardiovascular risk factors.
