At 6months, the mean difference in BMI for the intervention
vs control groups was −0.40. This magnitude of effectwas
similar to a recent community-based obesity prevention intervention
for Latino American familieswith preschool-aged
children (Salud Con La Familia) in which the adjusted mean
difference was −0.59 (95% CI, −0.94 to −0.25) at 3 months.45
Like our intervention, the Salud Con La Familia intervention
was culturally tailored and addressed family meals and TV
viewing. It is unclear as to the intervention effect of Salud Con
La Familia on these household routines as these datawere not
provided. Our findings suggest that a home-based intervention
that uses motivational interviewing to elicit change in
household routines, in particular aroundTVviewing and sleep
duration, is effective in reducing child’s BMI.
