Abstract
Indigenous inhabitants of the Arctic zone the use of an open hearth, portable stoves for heating leads to a high load of pollutants, that combined with the cold what can cause the activation of peroxidation. It is possible to prevent activation with the help of traditional nutrition (raw fish, venison), with high antioxidant activity (vitamins A, ω-3).
Our study aimed to develop risk models to determine the minimum sufficient rates of venison and fish consumption and to prevent the development of chronic nonobstructive bronchitis in reindeer herders.
616 reindeer herders (26.8% of men) aged 30-59 (mean age – 42.2), that is 8.0% of the total adult population of the district, participated in a cross-sectional study. The analysis of the diet was conducted using questionnaires. Nonlinear logit regression was used to build risk models. Permissible minimum amount of venison and fish was calculated to reduce the risk. The diagnosis of chronic nonobstructive bronchitis was established according to WHO definition. Lung function was assessed by a dry spirometer (SpiroUSB ML 2525 CareFusion, UK).
To reduce the risk of developing chronic nonobstructive bronchitis, minimum sufficient daily portion of deer meat should be at least 190 grams (OR=1.5), cheek – 158 grams (OR=1.5), pikes – 40 grams (OR=4.2, 95% CI–1.3–10.2). Eating venison and pike 2 times a week, a cheek – every other day is considered to be enough.
To conclude, adequate use of traditional food reduces the risk of chronic nonobstructive bronchitis.
