Body Weight, Physical Activity, and Risk of Cancer in Lynch Syndrome

Lynch syndrome (LS) increases cancer risk. There is considerable individual variation in LS cancer occurrence, which may be moderated by lifestyle factors, such as body weight and physical activity (PA). The potential associations of lifestyle and cancer risk in LS are understudied. We conducted a retrospective study with cancer register data to investigate associations between body weight, PA, and cancer risk among Finnish LS carriers. The participants (n = 465, 54% women) self-reported their adulthood body weight and PA at 10-year intervals. Overall cancer risk and colorectal cancer (CRC) risk was analyzed separately for men and women with respect to longitudinal and near-term changes in body weight and PA using extended Cox regression models. The longitudinal weight change was associated with an increased risk of all cancers (HR 1.02, 95% CI 1.00–1.04) and CRC (HR 1.03, 1.01–1.05) in men. The near-term weight change was associated with a lower CRC risk in women (HR 0.96, 0.92–0.99). Furthermore, 77.6% of the participants retained their PA category over time. Men in the high-activity group had a reduced longitudinal cancer risk of 63% (HR 0.37, 0.15–0.98) compared to men in the low-activity group. PA in adulthood was not associated with cancer risk among women. These results emphasize the role of weight maintenance and high-intensity PA throughout the lifespan in cancer prevention, particularly in men with LS

Perceived burden among spouse, adult child, and parent caregivers

Aims: To identify what factors are associated with the caregiver burden of spouse caregivers, adult child caregivers and parent caregivers. Background: Caregivers often feel stressed and perceive caregiving as a burden. The caregiver burden has been little studied from the perspective of the personal relationship between caregiver and care recipient. Design: Cross-sectional study Methods: A random sample of 4 000 caregivers in Finland was drawn in 2014 and those who remained either spouse, adult child or parent caregivers at data collection were included in the analysis (n=1 062). Data on the care recipients’ characteristics were also collected. Caregivers’ perceived burden was measured using the Caregivers of Older People in Europe index. General linear models were used to explain perceived caregiver burden. Results: Care recipients’ low level of cognitive function was associated with greater perceived burden. Higher quality of support was associated with lower perceived burden among female and male spouse caregivers, daughter caregivers and mother caregivers. Low cognitive function explained three to six percent and high quality of support two to five percent of the total variation in the burden explained by the models, which ranged between forty-five and fifty-five percent. Conclusion: Because cognitive challenges of care recipient are associated with greater perceived burden and high quality of support with lower burden among most of the caregiver groups, high quality tailored nursing interventions will be needed especially for the caregivers of the most frail care recipients
