Higher Resting Metabolism Is Associated With Increased Free Triiodothyronine Among Female Reindeer Herders in Northern Finland
Background Thyroid hormones (TH) regulate metabolism and are shaped by environmental factors—ambient temperature in particular. Previous work among indigenous and non‐indigenous populations in Russia revealed that there are seasonal shifts in TH dynamics such that total and free triiodothyronine (fT 3 ) and free thyroxine (fT 4 ) increase during winter. Elevated TH levels in these populations were positively correlated with the elevated resting m…
Total Energy Expenditure and Physical Activity Profiles Among Reindeer Herders and Office Workers of Northern Finland
With the seasonal nature of reindeer herding, February is a period of relative ease following the physically demanding round-up period that lasts from September to January, which may explain these results. Furthermore, large variation in the main variables of eTEE and PAL highlights the need for a larger study population. Therefore, a seasonal assessment of PA and eTEE patterns in this unique population where herders and office workers live close…
Reindeer herders from subarctic Finland exhibit high total energy expenditure and low energy intake during the autumn herd roundup
High TEE and low caloric intake among herders reflect the extreme demands placed on herders during the annual herd round up. Although TEE DLW was similar between cold climate herders and hot climate farming populations, there are likely differences in how that TEE is comprised, reflecting the local ecologies of these populations
Elevated resting metabolic rates among female, but not male, reindeer herders from subarctic Finland
OBJECTIVE: Elevated resting metabolic rates (RMR, kcal/day) are a well-established mechanism for maintaining core body temperature among cold climate populations. A high degree of interindividual variation has recently been noted among circumpolar populations. To further examine RMR variability, we investigated anthropometric and metabolic differences among reindeer herders from subarctic Finland. METHODS: Resting metabolic rates, body mass, body…
