“…By use of questionnaire, subjects may overestimate their activity levels (52). However, the HUNT questionnaires have been validated and associated with physical fitness (36)(37)(38). Also, it seems likely that any measurement error in the assessment of LTPA should not depend on menstrual status 10 years later and would often tend to bias results toward the null.…”

Background: Long menstrual cycles have been associated with anovulation, infertility and spontaneous abortion. Elite athletes have been found at risk of menstrual dysfunction. We evaluated the longitudinal association between leisure time physical activity (LTPA) and menstrual function in healthy non-athletic women. Methods: A population-based health survey (HUNT 1) was conducted during [1984][1985][1986] in Nord-Trøndelag county, Norway, with follow-up in 1995-1997 (HUNT 2). The current study included 3,097 women, <45 years old in HUNT 2. LTPA was assessed by questionnaire in HUNT 1, and menstrual function by questionnaire in HUNT 2. Data focused on overall occurrence of menstrual disorders in the population. Results were adjusted for age, education, psychological health, smoking and alcohol intake. Additional analyses included BMI as a potential confounder. Results: The median cycle length was 30 days and median number of days bleeding was 5. In women with normal cycle length, mean (SD) cycle length and duration of bleeding was 29.3 (2.8) and 5.6 (1.7) respectively. Cycle length increased with higher frequency of LTPA for women >25 years old. Women, 20-25 years old at baseline who were active most days had increased odds of short cycles, more bleeding days and increased odds of having irregular cycles, OR=4.7; 95% CI = 1.2-18.0). Number of bleeding days decreased with longer duration (p<0.05) and higher intensity (p=0.065) in young women. Adjustment for BMI did not affect the results. Conclusion: Leisure time physical activity may affect menstrual function, although in our study, the results were modified by age.

“…The LTPA questions have been validated for men with good test-retest reliability and validity (36,37) and partly in a small sample of women (38) where a positive association was found between reported intensity and oxygen uptake during exercise.…”

“…The questions were similar to those used in The HUNT study, which is a longitudinal population health study in Norway 29. There are five alternatives for reporting frequency of exercise from “never” to “almost every day.” There are three alternatives for intensity from “I take it easy without breaking into a sweat or losing my breath” to “I push myself to near exhaustion,” and four response alternatives for duration of each exercise session from “<15 min” to “[mt]1 h.” These questions have been validated 29. Feedback from patients have shown that one of the new statements was difficult to understand (I feel/notice pain).…”

ObjectiveCompulsive exercise is a well‐known feature in eating disorders. The Exercise and Eating Disorder (EED) self‐report questionnaire was developed to assess aspects of compulsive exercise not adequately captured by existing instruments. This study aimed to test psychometric properties and the factor structure of the EED among women with eating disorders and a control group.MethodThe study included 449 female participants, including 244 eating disorders patients and 205 healthy controls. The patient group consisted of 32.4% (n = 79) AN patients, 23.4% (n = 57) BN, 34.4% (n = 84) EDNOS and 9.8% (n = 24) with BED diagnosis.ResultsThe analyses confirmed adequate psychometric properties of the EED, with a four‐factor solution: (1) compulsive exercise, (2) positive and healthy exercise, (3) awareness of bodily signals, and (4) weight and shape exercise. The EED discriminated significantly (p < .001) between patients and controls on the global score, subscales, and individual items. Test‐retest reliability was satisfactory (r = 0.86). Convergent validity was demonstrated by high correlations between the EED and the Eating Disorder Examination Questionnaire (EDE‐Q; r = 0.79).DiscussionThe EED is the first clinically derived, self‐report questionnaire to assess compulsive exercise among ED patients. The EED offers assessment that has broader clinical utility than existing instruments because it identifies treatment targets and treatment priorities. © 2015 Wiley Periodicals, Inc.

“…When patients came to their 5-year follow-up visit, they filled out a validated self-reported physical activity questionnaire (77), and their current daily physical activity was also measured. The physical activity was measured by activity frequency and intensity, monitored with SenseWear armband monitors (BodyMedia Inc, Pittsburgh, USA) worn for one week (approximately 23h/day).…”

Background Peak oxygen uptake (VO2peak) is known as the gold standard measure of cardiopulmonary fitness. We therefore hypothesized that measures of physical health would predict long‐term survival in heart transplant recipients (HTx). Methods This retrospective study investigated survival in two HTx populations; the cardiopulmonary exercise test (CPET) cohort comprised 178 HTx patients who completed a VO2peak test during their annual follow‐up (1990–2003), and the SF‐36 cohort comprised 133 patients who completed a quality of life questionnaire, SF‐36v1 (1998–2000). Results Mean (SD) age in the CPET cohort was 52 (12) yr and 54 (11) yr in the SF‐36 cohort. Mean observation time was, respectively, 11 and 10 yr. Mean (SD) VO2peak was 19.6 (5.3) mL/kg/min, and median (IR) physical function (PF) score was 90 (30). VO2peak and PF scores were both significant predictors in univariate Cox regression. Multiple Cox regression analyses adjusted for other potential predictors showed that VO2peak, age, and cardiac allograft vasculopathy (CAV) were the most important predictors in the CPET cohort, whereas age, PF score, smoking, and CAV were the most important predictors in the SF‐36 cohort. In Kaplan–Meier analysis, VO2peak and PF scores above the median value were related to significant longer survival time. Conclusion Peak oxygen uptake and self‐reported physical health are strong predictors for long‐term survival in HTx recipients. VO2peak is a crucial measurement and should be more frequently used after HTx.
