A sleep duration of 6 hours or less or 9 hours or more is associated with increased prevalence of DM and IGT. Because this effect was present in subjects without insomnia, voluntary sleep restriction may contribute to the large public health burden of DM.
Usual sleep duration above or below the median of 7 to less than 8 hours per night is associated with an increased prevalence of hypertension, particularly at the extreme of less than 6 hours per night.
Sleep and sedentary and active behaviors are linked to cardiovascular disease risk biomarkers, and across a 24-hour day, increasing time in 1 behavior requires decreasing time in another. We explored associations of reallocating time to sleep, sedentary behavior, or active behaviors with biomarkers. Data (n = 2,185 full sample; n = 923 fasting subanalyses) from the cross-sectional 2005-2006 US National Health and Nutrition Examination Survey were analyzed. The amounts of time spent in sedentary behavior, light-intensity activity, and moderate-to-vigorous physical activity (MVPA) were derived from ActiGraph accelerometry (ActiGraph LLC, Pensacola, Florida), and respondents reported their sleep duration. Isotemporal substitution modeling indicated that, independent of potential confounders and time spent in other activities, beneficial associations (P < 0.05) with cardiovascular disease risk biomarkers were associated with the reallocation of 30 minutes/day of sedentary time with equal time of either sleep (2.2% lower insulin and 2.0% lower homeostasis model assessment of β-cell function), light-intensity activity (1.9% lower triglycerides, 2.4% lower insulin, and 2.2% lower homeostasis model assessment of β-cell function), or MVPA (2.4% smaller waist circumference, 4.4% higher high-density lipoprotein cholesterol, 8.5% lower triglycerides, 1.7% lower glucose, 10.7% lower insulin, and 9.7% higher homeostasis model assessment of insulin sensitivity. These findings provide evidence that MVPA may be the most potent health-enhancing, time-dependent behavior, with additional benefit conferred from light-intensity activities and sleep duration when reallocated from sedentary time.
Objective
To describe how gender shapes the concerns and adaptations of long-term (> 5 years) colorectal cancer (CRC) survivors with ostomies.
Design
Qualitative study using content analysis of focus group content.
Setting
Member of Kaiser Permanente, residing in either Oregon, Southwest Washington State, or Northern California.
Sample
Four female and four male focus groups selected from quantitative survey participants with health-related quality of life (HRQOL) scores in the highest or lowest quartile.
Methods
Eight focus groups, discussed challenges of living with an ostomy. Content was recorded, transcribed, and analyzed using directive and summative content analysis.
Main Research Variables
HRQOL domains of physical, psychological, social and spiritual well being.
Findings
All groups reported avoiding foods that cause gas or rapid transit, and discussed how limiting the amount of food eaten controlled the output. All groups discussed physical activities, getting support from friends and family, and the importance of being resilient. Both genders identified challenges with sexuality/intimacy. Coping and adjustment difficulties were discussed by women with men only discussing these issues to a small extent. Difficulties with sleep were primarily identified by Low HRQOL women. Problems with body image and depression were discussed only by Low HRQOL women.
Conclusions
Common issues included diet management, physical activity, social support and sexuality. Women with low HRQOL discussed problems with depression, body image, and sleep.
Implications for Nursing
Application of these gender-based differences can inform educational interventions for CRC survivors with ostomies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
