Riktade hälsosamtal i Skåne: Analys av samtidig validitet hos frågor om självskattad fysisk aktivitet samt kartläggning av stillasittande

Sammanfattning: Background: “Targeted health dialogues” is a preventive method that aims to reduce the risk of cardiovascular disease and type 2 diabetes. It includes a health-survey containing physical activity (PA)-questions. Health region Skåne introduced the method 2020 and decided to add additional questions about PA and sedentary behavior (SB). With the wish to replace current validated PA-questions with new validated questions and describe SB. Aim: Analyze concurrent validity between the answers of the original PA-questions (kcal/week) in the method and new answers (activity-minutes/last 7-days) and describe SB (hours/day). Method: Quantitative cross-sectional study with non-random, appropriate selection. Participants were 40-year-old health dialogue-participants that consented to research. Data on kcal/week, activity-minutes/last 7-days, sedentary hours/day and basic characteristics were retrieved from digital health-survey. Agreement between PA-questions was analyzed by Cohen´s weighted kappa and intraclass correlation-coefficient (ICC). SB was presented with descriptive statistics and analyzed by Chi2-test, Fisher's-exact-test and independent t-test. Result: Weak agreement between the PA-questions was found (Kw=0,378; ICC=0,273). Participants born in Sweden were more sedentary than those born outside Sweden (p<0.001) and participants with high education were more sedentary compared with lower education (p=0.014). Significant associations were found between SB and BMI (p=0.028; dichotomized analysis). Sedentary participants (>9 hours/d) also had higher mean BMI compared to those who were less sedentary (29,0(SD5,7) and 26,7(SD5,2) respectively; p=0,008). Conclusion: Current PA-questions cannot be replaced in favor of new questions in their current form. Further validation studies are warranted, preferably using objective PA-measures. SB was significantly associated with country of birth, education level and BMI.
