Abstract

Objectives: This study aimed to identify main sex-specific correlates of cardiorespiratory fitness (CRF) in a population-based, urban sample of Swedish adults.

Design: Cross-sectional.

Setting: Multi-site study at university hospitals, data from the Gothenburg site.

Participants: A total of 5308 participants (51% women, aged 50-64 years) with a valid estimated VOmax, from submaximal cycle test, in the Swedish CArdioPulmonary bioImage Study (SCAPIS), were included.

Primary And Secondary Outcomes: A wide range of correlates were examined including (a) sociodemographic and lifestyle behaviours, (b) perceived health, anthropometrics and chronic conditions and (c) self-reported as well as accelerometer-derived physical activity and sedentary behaviours. Both continuous levels of estimated VOmax as well as odds ratios (OR) and confidence intervals (CI)s of low VOmax (lowest sex-specific tertile) were reported.

Results: In multivariable regression analyses, higher age, being born abroad, short education, high waist circumference, poor perceived health, high accelerometer-derived time in sedentary and low in vigorous physical activity, as well as being passive commuter, correlated independently and significantly with low VOmax in both men and women (OR range 1.31-9.58). Additionally in men, financial strain and being an ex-smoker are associated with higher odds for low VOmax (OR 2.15; 95% CI 1.33 to 3.48 and OR 1.40; 95% CI 1.09 to 1.80), while constant stress with lower odds (OR 0.61; 95% CI 0.43 to 0.85). Additionally in women, being a regular smoker is associated with lower odds for low VOmax (OR 0.64; 95% CI 0.45 to 0.92).

Conclusions: The present study provides important reference material on CRF and correlates of CRF in a general middle-aged population, which can be valuable for future research, clinical practice and public health work. If relations are causal, increased knowledge about specific subgroups will aid in the development of appropriate, targeted interventions.
