“…Lifetime PA and prostate cancer incidence and mortality N Orsini et al some differences in measurement error that were dependent on individual characteristics such as body mass index (Norman et al, 2001). We found that the reliability of the historical PA questionnaire was relatively high (Spearman -Brown reliability were 0.7 at both age 50 and 30 years) (Orsini et al, 2007).…”

“…The 7-day activity records were shown to correlate well with the total PA questionnaire data, with a Spearman correlation coefficient of 0.6. The reproducibility of total PA, as reflected by the Spearman correlation coefficient between the first questionnaire and that obtained 6 months later, was 0.65 (Norman et al, 2001).…”

“…The absolute intensity of activities, defined in multiples of the metabolic equivalent (MET, kcal kg À1 Â h) of sitting quietly for 1 h, was based on a compendium of PAs (Ainsworth et al, 2000). More details regarding the calculations and assigned intensity values used can be found elsewhere (Norman et al, 2001). The total PA scores at age 30 and 50 years, and at baseline age, were calculated by summing the products of duration and intensity for each PA type.…”

BACKGROUND: The possible benefit of lifetime physical activity (PA) in reducing prostate cancer incidence and mortality is unclear. METHODS: A prospective cohort of 45 887 men aged 45 -79 years was followed up from January 1998 to December 2007 for prostate cancer incidence (n ¼ 2735) and to December 2006 for its subtypes and for fatal (n ¼ 190) prostate cancer. RESULTS: We observed an inverse association between lifetime (average of age 30 and 50 years, and baseline age) total PA levels and prostate cancer risk. Multivariate-adjusted incidence in the top quartile of lifetime total PA decreased by 16% (95% confidence interval (CI) ¼ 2 -27%) compared with that in the bottom quartile. We also observed an inverse association between average lifetime work or occupational activity and walking or bicycling duration and prostate cancer risk. Compared with men who mostly sit during their main work or occupation, men who sit half of the time experienced a 20% lower risk (95% CI ¼ 7 -31%). The rate ratio linearly decreased by 7% (95% CI ¼ 1 -12%) for total, 8% (95% CI ¼ 0 -16%) for localised and 12% (95% CI ¼ 2 -20%) for advanced prostate cancer for every 30 min per day increment of lifetime walking or bicycling in the range of 30 to 120 min per day. CONCLUSION: Our results suggest that not sitting for most of the time during work or occupational activity and walking or bicycling more than 30 min per day during adult life is associated with reduced incidence of prostate cancer.

“…Multivariate HR estimates were adjusted for age (continuous variable), marital status (single, married, divorced or widower), education (less than high school, high school or university), total physical activity (p38.8 and 438.8 MET Â hour/days, measured as metabolic equivalents (Norman et al, 2001)), self-perceived health status (very good, good, average, bad or very bad), waist-to-hip ratio (o0.94, X0.94), smoking status (never, former or current), dietary supplement use (regular use, occasional use or no use), alcohol use (p5 and 45 g ethanol per day) and total energy of diet (quartiles). Multivariate HR estimates for RFS and Non-RFS were mutually adjusted.…”

Background/Objectives: To study quality of diet in relation to all-cause mortality, cardiovascular disease (CVD) and cancer mortality. Subjects/Methods: The population-based prospective Cohort of Swedish Men (COSM) included 40 837 men, 45-79 years of age, who filled in a FFQ (96 food items) and were CVD-and cancer-free at baseline. Quality of diet was assessed by Recommended Food Score (RFS) based on 36 items and Non-Recommended Food Score (Non-RFS) based on 16 items. Cox's proportional hazards regression models were used to estimate the hazard ratios (HRs) of mortality and 95% confidence intervals (CIs). Multivariate HRs for RFS and Non-RFS were adjusted for age, education, physical activity, martial status, self-perceived health status, smoking status, dietary supplements use, WHR, alcohol use, intake of energy and mutually adjusted. Results: Between 1998 and 2005, 4501 deaths from all-causes were registered. Between 1998 and 2003, there were 1394 CVD and 759 cancer deaths. High RFS (X28) compared with low (p20) was associated with lower risk of all-cause mortality (HR: 0.81; 95% CI: 0.71-0.91; P-value for trendo0.0001) and CVD mortality (HR: 0.71; 95% CI: 0.54-0.93; P-value for trend ¼ 0.003). In contrast, men with high Non-RFS (X5) had higher risk of all-cause (HR: 1.21; 95% CI: 1.09-1.34; P-value for trend ¼ 0.001) and CVD mortality (HR: 1.27; 95% CI: 1.05-1.54; P-value for trend ¼ 0.07) compared to those with low Non-RFS (p2 items). No significant associations with cancer mortality were observed. Conclusions: Both measures of diet quality, RFS and Non-RFS, showed statistically significant associations with all-cause and CVD mortality (recommended foods inversely while nonrecommended foods positively), but not with cancer mortality.

Objective: The Nordic Nutrition Recommendations (NNR) aim at preventing dietassociated diseases such as cancer in the Nordic countries. We evaluated adherence to the NNR in relation to prostate cancer (PC) in Swedish men, including potential interaction with a genetic risk score and with lifestyle factors. Design: Population-based case-control study (Cancer of the Prostate in Sweden (CAPS), [2001][2002]. Using data from a semi-quantitative FFQ, we created an NNR adherence score and estimated relative risks of PC by unconditional logistic regression. Individual score components were modelled separately and potential modifying effects were assessed on the multiplicative scale. Setting: Four regions in the central and northern parts of Sweden. Subjects: Incident PC patients (n 1386) and population controls (n 940), frequencymatched on age and region. Results: No overall association with PC was found, possibly due to the generally high adherence to the NNR score and its narrow distribution in the study population. Among individual NNR score components, high compared with low intakes of polyunsaturated fat were associated with an increased relative risk of localized PC. No formal interaction with genetic or lifestyle factors was observed, although in stratified analysis a positive association between the NNR and PC was suggested among men with a high genetic risk score but not among men with a medium or low genetic risk score. Conclusions: Our findings do not support an association between NNR adherence and PC. The suggestive interaction with the genetic risk score deserves further investigations in other study populations.
