RESUMEN
Background:Menstrual cycle length is an indicator of reproductive health of a woman. Duration of menstrual cycle in a womanis affected by a number of factors including BMI. The effect of BMI on menstrual cycle length has been studied less extensively. Not many studies have been conducted on Indian populations. This study was conducted to study the relation of body mass index and menstrual cycle length in reproductive age women. Methods:The study included 225 women of age 15-45 years. Women with average menstrual cycle length of 24-38 were regarded as regularly menstruating women. Menstrual cycle length wasdefined as short (<24 days), normal (24-38 days), long (>38 days). During the menstrual phase of the cycle BMI of each participant was recorded.Results:A significant (p=0.0008) increase in mean BMI was found with increased in length of menstrual cycle. The majority of thewomen with long menstrual cycle were obese compared to women having normal and short length of menstrual cycle.Conclusions: The results of present study indicates that women with long menstrual cycle have increased body mass index compared to women having normal or short menstrual cycle length.
RESUMEN
ABSTRACT BACKGROUND: The aim here was to study acute effects of hemodialysis among end-stage renal disease (ESRD) patients. DESIGN AND SETTING: Prospective study in tertiary-level care center. METHODS: Fifty ESRD patients undergoing hemodialysis were studied. Spirometric pulmonary function tests were performed before and after four-hour hemodialysis sessions. RESULTS: The patients' average age was 45.8 ± 10.0 years; 64% were males and 64% had normal body mass index. Anemia (94%) and hypoalbuminemia (72%) were common. Diabetes mellitus (68%), hypertension (34%) and coronary artery disease (18%) were major comorbidities. Forty-five patients (90%) had been on hemodialysis for six months to three years. The patients' pre-dialysis mean forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were below normal: 45.8 ± 24.9% and 43.5 ± 25.9% of predicted, respectively. After hemodialysis, these increased significantly, to 51.1 ± 23.4% and 49.3 ± 25.5% of predicted, respectively (P < 0.01). The increase in mean FEV1/FVC, from 97.8 ± 20.8% to 99.3 ± 20.1% of predicted, was not significant (P > 0.05). The pre-dialysis mean forced expiratory flow 25-75% was 50.1 ± 31% and increased significantly, to 56.3 ± 31.6% of predicted (P < 0.05). The mean peak expiratory flow was below normal (43.8 ± 30.7%) and increased significantly, to 49.1 ± 29.9% of predicted (P < 0.05). Males and females showed similar directions of change after hemodialysis. CONCLUSIONS: Pulmonary function abnormalities are common among ESRD patients. Comparison of pre and post-hemodialysis parameters showed significant improvements, but normal predicted values were still not achieved.
