Associations Between Paternal Pre‐Conceptional Body Mass Index and Lifestyle Factors and Offspring Weight Development
Authors' conclusion
Paternal BMI was associated with offspring outcomes at age 5 years, while findings for paternal dietary factors were less consistent.
Study context
- Population
- Father-child pairs from pregnancies among women with pre-pregnancy overweight or obesity; paternal characteristics reported at gestational week 15
- Participants
- 162 father-child pairs
Primary result
As reported in the abstract
Associations of paternal BMI, protein intake, GI, smoking and alcohol with offspring weight development · birth to 5 years
- Age 5: higher paternal BMI and offspring BMI z-score, β
- 0.07 (0.03; 0.10) (CI)
- Age 5: higher paternal BMI and offspring fat mass index, β
- 0.07 kg/m² (0.02; 0.12) (CI)
- Age 5: higher paternal BMI and offspring fat-free mass index, β
- 0.05 kg/m² (0.01; 0.08) (CI)
- Age 5: lower paternal protein intake and offspring BMI z-score, β
- 0.54 (0.07; 1.01) (CI)
- Age 5: lower paternal protein intake and offspring fat-free mass index, β
- 0.60 kg/m² (0.13; 1.07) (CI)
- Age 5: moderately higher paternal protein intake and offspring WHR (waist-to-height ratio), β
- 0.03 (3.00 × 10-3; 0.05) (CI)
- Age 5: higher paternal glycemic index (GI) and offspring BMI z-score, β
- −0.04 (−0.08; −2.14-10-3) (CI)
