Determinants of Weight Loss in an Interdisciplinary Long-Term Care Program for Childhood Obesity

Table 2

Influence of medical factors assessed at the first visit on the weight change observed at 9 months of intervention.

Factors studied	No/low	Intermediate	Yes/high	𝑃 value
Significative
Physical activity^a	−0.18 ± 0.04	−0.30 ± 0.05	−0.42 ± 0.11	𝑃=0.037
Delayed puberty^b	−0.23 ± 0.03		−0.02 ± 0.10	𝑃=0.046
Nonsignificative
Birthweight (>4000 g)	−0.21 ± 0.03		−0.31 ± 0.11	𝑃=0.37 NS
Gestational diabetes	−0.23 ± 0.04		−0.02 ± 0.14	𝑃=0.15 NS
Breastfeeding (≥6 months)	−0.20 ± 0.04		−0.30 ± 0.07	𝑃=0.21 NS
Obesity in the family^c	−0.21 ± 0.05		−0.18 ± 0.04	𝑃=0.62 NS
Asthma	−0.21 ± 0.03		−0.37 ± 0.11	𝑃=0.18 NS
Bad quality of sleep^d	−0.18 ± 0.05		−0.13 ± 0.07	𝑃=0.61 NS

Data are expressed as change in mean BMI-z-score ± SEM at 9 months of intervention. 𝑃<0.05, significant. NS: not significant.
^aPhysical activity means that the child joins a sport club or a youth organization at least twice a week (yes/high); once a week (intermediate) or never (no/low).
^bDelayed puberty was considered when a girl was assessed M1>13.5 years or a boy was assessed G1>14 years.
^cObesity in the family means that the child has at least one of the two parents who is obese (BMI > 30 kg/m²).
^dBad quality of sleep was assessed by snoring or short sleep duration (<9 h/night). This information was not available for all the patients (𝑛=76).
