Obesity, high energy intake, lack of physical activity, and the risk of kidney cancer.

The authors conducted a population-based case-control study of 810 cases with histologically confirmed incident kidney cancer and 3,106 controls to assess the effect of obesity, energy intake, and recreational physical activity on renal cell and non-renal cell cancer risk in Canada from 1994 to 1997. Compared with normal body mass index (BMI; 18.5 to <25.0 kg/m2), obesity (BMI, >or=30.0 kg/m2) was associated with multivariable-adjusted odds ratios (OR) and 95% confidence intervals (95% CI) of 2.57 (2.02-3.28) for renal cell cancer and 2.79 (1.70-4.60) for non-renal cell cancer. The OR (95% CI) associated with the highest quartiles of calorie intake was 1.30 (1.02-1.66) for renal cell cancer and 1.53 (0.92-2.53) for non-renal cell cancer. Compared with the lowest quartile of total recreational physical activity, the highest quartile of total activity was associated with an OR (95% CI) of 1.00 (0.78-1.28) and 0.79 (0.46-1.36) for the two subtypes. There were no apparent differences between men and women about these associations. The influence of obesity and physical activity on the risk of renal cell and non-renal cell cancer did not change by age, whereas the effect of excess energy intake was stronger among older people. No significant effect modifications of physical activity on BMI among both genders and of energy intake on BMI among men were observed, with a synergic effect of obesity and high energy intake on renal cell cancer risk found among women. This study suggests that obesity and excess energy intake are important etiologic risk factors for renal cell and non-renal cell cancer. The role of physical activity needs further investigation.

Morbidity Experiences and Disability Among Canadian Women.

HEALTH ISSUE: Women are more frequently affected by chronic conditions and disability than men. Although some of these sex differences have been in part attributed to biological susceptibility, social determinants of health and other factors, these gaps have not been fully explained in the current literature. This chapter presents comparisons of hospitalization rates, and the prevalence of chronic conditions and physical disability between Canadian women and men and between various subgroups of women, adjusting for selected risk factors. The Canadian Hospital Morbidity Database (2000-2001) and Canadian Community Health Survey (2000-2001) were used to examine inpatient hospital morbidity, prevalence of chronic conditions and disability. KEY FINDINGS: Hospitalization rates were 20% higher among women than men. This was due to the large number of hospitalizations for pregnancies and childbirth. When "normal" deliveries were excluded, hospitalization rates remained higher among women. Women had slightly lower rates of hospitalizations for ambulatory-care sensitive conditions than men. Prevalence of activity limitation (mild and severe) was higher among women than men, and differences remained after adjusting for age, chronic conditions, socio-economic status, and smoking. Women who reported a disability were less likely than men to be in a partnered relationship, have less tangible social support, and have lower income and employment rates. DATA GAPS AND RECOMMENDATIONS: The impact of morbidity and disability on Canadian women is substantial. These results identify areas for interventions among more vulnerable subgroups, and point to the need for further research in the area of risk factors for the prevention of morbidity and disability in the population.

Chronic Pain: The Extra Burden on Canadian Women.

HEALTH ISSUE: Chronic pain is a major health problem associated with significant costs to both afflicted individuals and society as a whole. These costs seem to be disproportionately borne by women, who generally have higher prevalence rates for chronic pain than do men. KEY FINDINGS: Data obtained from 125,574 respondents to the Canadian Community Health Survey (2000-2001) indicated that 18% of Canadian women suffered from chronic pain, compared to 14% of men. This gender discrepancy, however, seemed to be linked primarily to differences in age, income, and education between adult men and women in this large sample. Age, income, depression and functional interference with activities were strongly associated with chronic pain in general. No gender differences were found in the intensity of pain experienced. Ethnicity was not strongly associated with chronic pain prevalence, although Asians were the group with the highest chronic pain prevalence in the over-65 age group and Aboriginal Canadians had the highest prevalence in the under-65 age group. DATA GAPS AND RECOMMENDATIONS: Current gaps in our knowledge include the types of chronic pain women experience, their impact on domestic responsibilities and parenting and health care utilization patterns of women with chronic pain. Data sources such as provincial databases of billing claims may be useful in the future to enrich our knowledge of health care utilization and analgesic medication use. Enhanced surveillance, assessment, and early identification of pain disorders are recommended to improve outcomes. Considering current demographic patterns toward an older population, there is also some urgency to the development of patient education and self-management programs.

Factors Associated with Women's Medication Use.

HEALTH ISSUE: Research has consistently shown that while women generally live longer than men, they report more illness and use of health care services (including medication). In the literature, the reasons for women's elevated medication use are not clear. This paper investigates the associations between over-the-counter (OTC) and prescription (Rx) medication use and selected social and demographic variables in men and women. KEY FINDINGS: While a larger proportion of women than men used medication throughout the study, the proportion of people using medication did not increase. The use of OTC and Rx medication increased by number of physician visits for women and men.Medication use increased with age, chronic disease and number of physician visits, and decreased with the perception of good to excellent health. The relationship with other factors varied for women and men depending on their education level, income and social roles. For women, the social roles of being married or previously married, being employed or being a parent did not increase their likelihood of medication use. Reported income adequacy is not associated with the chances of mediation use among highly educated women, but for women with low levels, medication use increases as income adequacy decreases. DATA GAPS AND RECOMMENDATIONS: More complete data are needed about social roles and their relation to mediation use. Data that would allow an assessment of the appropriateness of OTC and Rx drug use or the reasons for such use need to be collected. More research is needed to better understand the distribution and determinants of specific medication use.

Mortality: life and health expectancy of Canadian women.

HEALTH ISSUE: The sex differences in mortality, life expectancy, and, to a lesser extent, health expectancy, are well recognized in Canada and internationally. However, the factors explaining these differences between women and men are not well understood. This chapter explores the contribution of various causes of death (such as preventable, and sex-specific deaths) on these differences between women and men. KEY FINDINGS: "External" preventable causes of death (e.g. smoking-related, injuries, etc.) were responsible for a large portion of the sex gap in mortality and life expectancy. When excluding these causes from the calculations, the sex gap in life expectancies were largely reduced, decreasing from approximately 5.5 years (life expectancy being 81.4, years in women, and 75.9 years in men) to approximately 2.2 years (84.9 in women and 82.7 in men). Sex gaps in corresponding health expectancies entirely disappeared when these preventable causes of death were excluded. Moreover, a larger death burden was observed among women than men for sex-specific causes of death (eg. excess breast cancer, gynaecological cancers, maternal mortality). Significant disparities were also observed in the mortality rates of various subgroups of women by geographic regions of Canada. DATA GAPS AND RECOMMENDATIONS: These results indicate that women do not appear to have a large biological survival advantage but, rather, are at lower risk of preventable deaths. They also provide additional information needed for the development of policies aimed at reducing disparities in life and health expectancies in Canada and other developed countries.

New approaches to immigrant health assessment.

While immigrant subgroups may present vulnerabilities in terms of health status, health service use, and social determinants, comprehensive information on their health is lacking. To examine mortality (1980-1998) and health service utilization (1985-2002) patterns in Canadian immigrants, a record linkage pan-Canadian research initiative using immigration and health databases has been undertaken. Preliminary results indicate that overall mortality is low among Canadian immigrants as compared to the general population for most leading causes (thus supporting the notion of "healthy immigrant effect"), with cause-specific exceptions. Moreover, results from British Columbia show that overall physician visits are low for immigrants, but not for all subgroups. Results from Ontario demonstrate a sharp increase in physician claims approximately three months following landing. Future analyses will address the short- and long-term health outcomes of immigrant subgroups, including less common diseases. Results are pertinent to practitioners working with immigrants and can inform immigrant health policy.
