The effect of initial support on fitness center use in new fitness center members. A randomized controlled trial.

This provider and participant blinded parallel-group randomized controlled trial aimed to investigate if initial support given to new members via telephone and e-mail, compared to self-directed use, had an effect on booking with a fitness trainer, number of visits to the center, and membership duration. Participants included 356 new members, 174 randomized to the intervention group, and 182 to the control group. The intervention group received support to use the fitness center facilities through two phone calls and one e-mail over the first eight weeks of their membership. The control group got usual practice, which is self-directed use. Participants in the intervention group were more likely to book at least one session with a fitness trainer during the first six months (odds ratio 1.6, 95% confidence interval (CI) 1.0-2.5). However, the intervention did not influence the number of visits (mean difference after four years -11.7 days, 95% CI -34.8 to 11.3) or time to membership termination during the follow-up period (hazard ratio 1.1, 95% CI 0.8-1.3). In conclusion, initial support to use the fitness center facilities given to new fitness center members via telephone and e-mail increased the proportion of bookings with a fitness trainer during the first months of the membership, but it did not have an effect on the number of visits or membership termination during four years.

Physical activity after inpatient occupational rehabilitation: Secondary outcomes of two randomized controlled trials.

OBJECTIVES: To assess whether inpatient multicomponent occupational rehabilitation, including physical activity (PA), increases the PA level of participants more than an outpatient program without PA, and whether changes in PA are associated with future work outcomes. METHODS: A total of 265 participants were included in one of two randomized clinical trials. Participants had been sick listed 2-12 months with a musculo-skeletal, psychological, or general/unspecified diagnosis. We measured PA by questionnaires at the start of the programs and at 3, 6, and 12 months of follow-up. Between-group differences in PA were assessed using linear mixed models. Associations between change in PA and future work outcomes were assessed by logistic and linear regression. RESULTS: There was no difference in change in PA between the inpatient and outpatient programs during 12 months of follow-up. We did not find any associations between the amount of PA and future work outcomes. However, intensity of PA was positively associated with return to work (RTW); participants reporting increased vigorous PA had an odds ratio (OR) for RTW of 4.1 (95% confidence interval [CI] 1.1-15.7) whereas participants reporting consistently high intensity of PA had an OR of 3.1 (95% CI 1.0-9.7), compared to participants reporting low-intensity PA. CONCLUSION: Inpatient occupational rehabilitation, including PA, did not increase PA-level in the follow-up period more than a less comprehensive program without PA. The amount of PA was not associated with future work outcomes. However, vigorous PA showed a positive association with RTW.

Does 'existential unease' predict adult multimorbidity? Analytical cohort study on embodiment based on the Norwegian HUNT population.

OBJECTIVES: Multimorbidity is prevalent, and knowledge regarding its aetiology is limited. The general pathogenic impact of adverse life experiences, comprising a wide-ranging typology, is well documented and coherent with the concept allostatic overload (the long-term impact of stress on human physiology) and the notion embodiment (the conversion of sociocultural and environmental influences into physiological characteristics). Less is known about the medical relevance of subtle distress or unease. The study aim was to prospectively explore the associations between existential unease (coined as a meta-term for the included items) and multimorbidity. SETTING: Our data are derived from an unselected Norwegian population, the Nord-Trøndelag Health Study, phases 2 (1995-1997) and 3 (2006-2008), with a mean of 11 years follow-up. PARTICIPANTS: The analysis includes 20 365 individuals aged 20-59 years who participated in both phases and was classified without multimorbidity (with 0-1 disease) at baseline. METHODS: From HUNT2, we selected 11 items indicating 'unease' in the realms of self-esteem, well-being, sense of coherence and social relationships. Poisson regressions were used to generate relative risk (RR) of developing multimorbidity, according to the respondents' ease/unease profile. RESULTS: A total of 6277 (30.8%) participants developed multimorbidity. They were older, more likely to be women, smokers and with lower education. 10 of the 11 'unease' items were significantly related to the development of multimorbidity. The items 'poor self-rated health' and 'feeling dissatisfied with life' exhibited the highest RR, 1.55 and 1.44, respectively (95% CI 1.44 to 1.66 and 1.21 to 1.71). The prevalence of multimorbidity increased with the number of 'unease' factors, from 26.7% for no factor to 49.2% for 6 or more. CONCLUSIONS: In this prospective study, 'existential unease' was associated with the development of multimorbidity in a dose-response manner. The finding indicates that existential unease increases people's vulnerability to disease, concordant with current literature regarding increased allostatic load.

A prospective population-based cohort study of lactation and cardiovascular disease mortality: the HUNT study.

BACKGROUND: Recent studies suggest that lactation has long-term effects on risk for cardiovascular disease in women, but the effects on cardiovascular mortality are less well known. METHOD: In a Norwegian population-based prospective cohort study, we studied the association of lifetime duration of lactation with cardiovascular mortality in 21,889 women aged 30 to 85 years who attended the second Nord-Trøndelag Health Survey (HUNT2) in 1995-1997. The cohort was followed for mortality through 2010 by a linkage with the Cause of Death Registry. Adjusted hazard ratios (HR) for death from all causes and cardiovascular disease were calculated using Cox regression. RESULTS: During follow-up, 1,246 women died from cardiovascular disease. Parous women younger than 65 years who had never lactated had a higher cardiovascular mortality than the reference group of women who had lactated 24 months or more (HR 2.77, 95% confidence interval [CI]: 1.28, 5.99). There was some evidence of a U-shaped association, where women who reported lactating 7-12 months had a HR of 0.55 (95% CI: 0.27, 1.09). No clear associations were observed among women 65 years or older. CONCLUSIONS: Excess cardiovascular mortality rates were observed among parous women younger than 65 years who had never lactated. These findings support the hypothesis that lactation may have long-term influences on maternal cardiovascular health.

Parent-held child health records do not improve care: a randomized controlled trial in Norway.

OBJECTIVE: To study the effects of a parent-held child health record (PHCHR) that was created by the Norwegian Board of Health with the purpose of introducing this to the whole country. DESIGN: Randomized controlled trial. SETTING: Maternal and child health centres in 10 municipalities in Norway. SUBJECTS: Parents of 309 children attending the National Preschool Health Surveillance Programme. INTERVENTION: Half of the parents were given a PHCHR and short instructions on how it was expected to be used. MAIN OUTCOME MEASURES: Parent-professional collaboration, healthcare utilization, and parents' knowledge about child health matters and illness. RESULTS: Some 73% of the intervention group used the PHCHR regularly when visiting the health centres, 79% reported that their own writing in the record was helpful, and 92% favoured the PHCHR being permanently adopted. Use of the record did not influence the utilization of healthcare services, parents' knowledge of their child's health, or parents' satisfaction with information or communication with professionals. CONCLUSIONS: The PHCHR was well accepted by parents and professionals but it had no effects on collaboration, healthcare utilization, or other measures that could justify the costs of introducing the record into common use. Therefore, the introduction of a parent-held child health record in Norway is being postponed.
