Sleep, physical activity, waist circumference and diet as factors that influence health for reproductive age women in northern Greenland.

BACKGROUND

This study explored community and individual factors that influence the health of reproductive age women in a settlement in northern Greenland. This is important because Greenland has a declining population, a high abortion rate and because of projected environmental shifts due to climate change.

METHODS

This study collected mixed methods data to explore diet, physical activity, sleep and waist circumference for reproductive age women in Kullorsuaq, Greenland. The daily steps and sleeping hours of 13 reproductive age women were measured using activity monitoring bracelets. Waist circumference measurements and in-depth interviews about daily eating and physical activity were conducted with 15 participants and ethnographic participant observations were recorded using field notes.

RESULTS

Waist circumference measurements were above recommended cutoffs established by the World Health Organization. Physical activity measured by daily steps was within the 'active' range using the cutoff points established by Tudor and Locke. Physical activity is social and is important for communal relationships. Sleeping hours were within normal ranges based on US guidelines; however, the quality of this sleep, its variability across seasons and cultural expectations of what healthy sleep means must be further explored. Diets of women included a mixture of locally harvested meats and imported packaged foods. Study participants experienced less satiety and reported getting hungrier faster when eating packaged foods. This research took place in Spring 2016 and women reported that their sleep, physical activity and diet fluctuate seasonally.

CONCLUSION

The reported findings suggest further investigation of sleep, diet and physical activity combined with the measurement of reproductive hormones to determine linkages between lifestyle factors and reproductive health outcomes is needed.
