“…We found an increase in BMI over the follow-up period, in accordance with a global trend of increasing BMI over decades, including northern Norway [18,19], which raises concerns considering the relationship with diabetes, cardiovascular diseases and all-cause mortality [20–23]. As expected, we found that BMI increased most among those who were persistently inactive.…”

Objective: The aim of this study was to examine the associations between changes in leisure time physical activity and changes in cardiovascular risk factors over 16 years and whether they differ between two ethnic groups in Norway.Methods: Data were extracted from two population-based studies. Altogether, 3671 men and women participated in both surveys, and 30% reported being of Sami ethnicity. Leisure time physical activity was self-reported, and cardiovascular risk factors were measured. ANCOVA analysis was used to examine associations between changes in physical activity and changes in cardiovascular risk factors.Results: After adjustment for age, sex, smoking, ethnicity and respective baseline values, favourable changes in body mass index (BMI) and levels of triglycerides were most pronounced in those who were active in both surveys (p < 0.05) whereas the opposite was the situation for cholesterol levels (p = 0.003). Changes in systolic blood pressure, diastolic blood pressure and resting heart rate were not significantly associated with change in physical activity. Ethnicity did not influence the associations between physical activity and cardiovascular risk factors.Conclusion: Traditional cardiovascular risk factors were to a small extent associated with change in leisure time physical activity. Persistent physical activity was associated with beneficial changes in BMI and triglycerides.

“…Our results show that the mean adult body weight in Norwegian women increased during the study period and that younger women gained more weight than older, which is in accordance with other studies [18,19,20,21]. It is challenging to compare the mean annual weight change between studies, as population age distribution and follow-up time may differ considerably.…”

Aim: To identify factors associated with high weight gain and obesity duration in a representative sample of Norwegian women. Methods: 66,618 Norwegian women aged 34-70 years at baseline were included in the analysis. Baseline and follow-up questionnaires completed in 1991-2011 provided information on height, weight as well as sociodemographic, lifestyle and reproductive factors. We assessed the association with multivariable logistic regression. Results: Women gained on average 0.5 kg/year (95% CI 0.5-0.5 kg/year) during 6 years of follow-up, and 3.5% maintained in obesity during 13 years of follow-up. The factors with strongest association with high weight gain (≥10 kg) were smoking cessation (cessation vs. no change, OR = 4.39, 95% CI 3.91-4.94) and decreased physical activity level (decrease vs. no change, OR = 2.40, 95% CI 2.21-2.61). Low physical activity level (high vs. low, OR = 0.17, 95% CI 0.14-0.20), higher than median age at menarche (over median vs. median or under median, OR = 0.36, 95% CI 0.31-0.41), and less than 10 years of education (>12 years vs. <10 years, OR = 0.44, 95% CI 0.37-0.51) were strongly associated with obesity duration. Conclusion: The modifiable factor with the strongest association with adverse weight development and potential for prevention was low or decreased physical activity level.

“…This is in contrast with the study of Ogles et al [16] who found that women, more than men practiced running for weight control. This can be explained by the latest Norwegian data [9,10] witch says that 75% of adult males and 60% of adult females in Norway were found to be classified as overweight or obese. These reports make it logically expected that both males and females, especially males, are concerned in weight reduction activities.…”

The purposes of the present study was to investigate the motives for training and competing among participants in a half-marathon race. A descriptive quantitative research design was developed using a questionnaire to examine the half-marathon runners' interest in running and competition. The total number of participants presented in this study were 862, 331 female and 531 male with a mean age 41.8±10.4 years. The major reasons for the participants to regularly practice running were because of its importance to their physical and psychological health, because it is fun, and for other health reasons, respectively. Comparing the motives for running between males and females showed that males scored higher on health, losing weight and to be able to measure their running abilities with others. Comparing the main reasons among age groups for participating in half-marathon competition, the majority of the <40 years old participated to a greater extent to challenge themselves, to exercise and to experience nature, respectively, compared to >40 years old. The results indicate that the major reasons for regularly practice running are that running as activity is important for maintaining physical and physiological health.
