Self-reported leisure time physical activity: a useful assessment tool in everyday health care

Abstract

BackgroundThe individual physical activity level is an independent risk factor for cardiovascular disease and death, as well as a possible target for improving health outcome. However, today´s widely adopted risk score charts, typically do not include the level of physical activity. There is a need for a simple risk assessment tool, which includes a reliable assessment of the level of physical activity. The aim of this study was therefore, to analyse the association between the self-reported levels of physical activity, according to the Saltin-Grimby Physical Activity Level Scale (SGPALS) question, and cardiovascular risk factors, specifically focusing on the group of individuals with the lowest level of self-reported PA.MethodsWe used cross sectional data from the Intergene study, a random sample of inhabitants from the western part of Sweden, totalling 3588 (1685 men and 1903 women, mean age 52 and 51). Metabolic measurements, including serum-cholesterol, serum-triglycerides, fasting plasma-glucose, waist circumference, blood pressure and resting heart rate, as well as smoking and self-reported stress were related to the self-reported physical activity level, according to the modernized version of the SGPALS 4-level scale.ResultsThere was a strong negative association between the self-reported physical activity level, and smoking, weight, waist circumference, resting heart rate, as well as to the levels of fasting plasma-glucose, serum-triglycerides, low-density lipoproteins (LDL), and self-reported stress and a positive association with the levels of high-density lipoproteins (HDL). The individuals reporting the lowest level of PA (SGPALS, level 1) had the highest odds-ratios (OR) for having pre-defined levels of abnormal risk factors, such as being overweight (men OR 2.19, 95% CI: 1.51-3.19; women OR 2.57, 95 % CI: 1.78-3.73), having an increased waist circumference (men OR 3.76, 95 % CI: 2.61-5.43; women OR 2.91, 95% CI: 1.94-4.35) and for reporting stress (men OR 3.59, 95 % CI: 2.34-5.49; women OR 1.25, 95% CI: 0.79-1.98), compared to the most active individuals, but also showed increased OR for most other risk factors analyzed above.ConclusionThe self-reported PA-level according to the modernized Saltin-Grimby Physical Activity Level Scale, SGPALS, is associated with the presence of many cardiovascular risk factors, with the most inactive individuals having the highest risk factor profile, including self-reported stress. We propose that the present SGPALS may be used as an additional, simple tool in a routine risk assessment in e.g. primary care, to identify inactive individuals, with a higher risk profile.

Physical activity and the association with fatigue and sleep in Danish patients with rheumatoid arthritis

“…Furthermore, moderate to vigorous physical activity was lower for patients in our study compared to the general Danish population (21.6 vs. 29.2 %) [31]. However, the 2 % of the patients reporting physical activity at the highest level (level IV) was consistent with levels reported in studies carried out in the general population [32][33][34]. Thus, patients with RA may differ from the general population in particular through behavior that is more sedentary or at a low level of physical activity.…”

“…This risk of social desirability bias is well known when using self-report measures of physical activity and sedentary behavior. However, the Leisure Time Physical Activity Questionnaire developed by Saltin and Grimby has proven robust and independent of the context and been found to be appropriate for estimating cardiovascular morbidity [32,58] risk of death in a large Danish population-based study [59]. Nevertheless, for more precise measurement of the detailed physical activity level and patterns, studies including objective measures (e.g., accelerometers) are warranted.…”

Is preoperative physical activity related to post-surgery recovery?—a cohort study of colorectal cancer patients

“…If your activity varies greatly try to estimate an average.' The answering categories were as follows: The Saltin-Grimby Physical Activity Level Scale has been shown to have a high validity and reliability [24], being associated to objective measures of activity, cardiovascular risk factors [25,26], as well as morbidity [27,28] and mortality [29], and has been used in >500,000 patients in clinical studies [24]. The questionnaire referred to the last week before the patient answered.…”
