Multifactorial analysis of a mixed-longitudinal sample of Indian siblings: Age and sex effects on heritability

Heritability variations of body linearity and obesity indicators during growth

“…Although some studies (e.g. Mueller, 1977;Salces et al, 2009) have pointed out that this pattern for higher heritabilities for skeletal measurements than for muscle or/and fat related traits is not supported in growing children, the observations of this study are in line with the results reported by Arya et al (2002). According to these results, this gradient is observed in samples of growing children from six Andhra caste populations.…”

“…Longitudinal as well as cross-sectional studies have shown variations with age in heritability estimates from infancy to adulthood, even though the patterns of variation are not completely clear (Haworth et al, 2008;Heude et al, 2005;Lajunen et al, 2009;Rebato et al, 1997Rebato et al, , 2005Salces et al, 2009;Silventoinen et al, 2007Silventoinen et al, , 2008. In general, as in the present study (data not shown), the agepattern of genetic contribution estimates demonstrates a gradually increasing impact of the child's genotype Ulijaszek and Mascie-Taylor, 1994).…”

However, there has not been established yet a well-defined pattern of change for heritability values from infancy to adulthood.…”
