mothers and daughters in the city of Merida, Mexico, and determine if these
differences are associated to their childhood socioeconomic conditions. Methods
From September 2011 to January 2014, we measured KH and collected data on
childhood conditions (place of birth, type of drinking water, family size [FS] and
fathers’ occupation) from a sample of 180 Maya mother-daughter dyads. Mean
intergenerational difference in KH was calculated and compared for each category
of socioeconomic variables and a multiple regression model was adjusted to
assess the association between childhood conditions and difference in KH.
Results A relative increase of 1.05 cm (SD = 2.3 cm) or 0.45 standard deviations
(effect size of difference) was observed in KH between generations. Place of birth
and FS were significantly associated to KH. The intergenerational KH difference
was 1.6 cm longer when mothers were born outside Merida but daughters were
born in the city. Daughters with larger FS than their mothers associated to a
decrease in KH difference (1.6 cm) compared to daughters and mothers having the
same FS. Conclusions The relative represents a portion of the expected change in growth in a group that has
experienced few substantial improvements in their living conditions. Slight
improvements in childhood living conditions resulting from the intergenerational
transition from rural to urban environments seem to be linked to a slight
intergenerational increase in KH among Maya women in Merida.
