Key result
Village living is linked to ~9 bpm lower flex heart rates in boys versus urban peers.
Why the study?
Flex heart rate is increasingly important for studying energy expenditure and physical activity, but methodological and population variation issues remain unclear.
Population
80 Nepali boys aged 10-14 years from village, urban middle-class, and homeless street environments
Comparison
Flex HR values among village boys vs urban middle-class schoolboys vs homeless street boys
Design
Cross-sectional study with repeated measures for reliability in a subset
Follow-up
3 months for reliability assessment in 14 school boys

Environmental variation in flex HR among Nepali boys warrants cautious interpretation; cross-sectional data leave open causality and longitudinal stability.
Cross-Sectional (n=80)
Absolute Event Rate: 91% vs 100%
p-value: p=< 0.0001
Flex heart rate varies significantly across different socioeconomic environments in Nepali boys and is reliable at the population level but not necessarily stable for individuals over time.
Panter‐Brick et al. (1996) reported a cross-sectional. Contrasting physical and socioeconomic environments vs. Between groups was evaluated on Flex heart rate (bpm) (p=< 0.0001). Flex heart rate in Nepali boys varied by environment, with village boys averaging lower values (91 bpm) than urban schoolboys (100 bpm) or homeless street boys (103 bpm) (P<0.0001).
