Specifically, some providers required women to monitor their cycle length for several months prior to initiating SDM; to be menstruating at the time they begin using the method; or to have their partner present during the counseling session.
We did not find significant differences in changes in Z-scores for body length and weight-for-length from months 3 to 9 according to maternal OGTT glucose concentrations at 26 30 gestational weeks.
To account for the unequal length of months, these were adjusted to a standard month of 30.44 (365.25/12) days.
Length (for children <24 months of age) and height (for children ≥24 months of age and women) will be measured using a baby mat and/or stadiometer measuring to 0.1 cm precision.
Only four (2%) of the infants' were below −2 SD weight-for-age and 2 (1%) were below −2 SD length-for-age at 6 months, indicating that the prevalence of underweight or stunting in our sample was very low.
All HCMV-seropositive infants had decreased length-for-age by 18 months compared with seronegative infants (standard deviation [ z]-score difference: −0.44 [95% confidence interval {CI}, −.72 to −.17]; P =.002).
The present study indicated that abnormal maternal glucose tolerance during pregnancy was associated with larger birth weight and birth length, lower length-for-age Z-score at months 3, 6, 9, and 12 of age, and more weight gain in the months 9 12 of life.
Mean Z-scores at 6, 9, 12 and 18 months for length-for-age, weight-for-age and weight-for-length will be determined as well as changes in Z-scores over 12 months.
Considering the effect of previous weight or length, we analyzed percentage change of Z-scores (change in Z-score between present and previous Z-scores accounting for previous Z-score) for weight-for-age and length-for-age for each three months from birth to month 12 according to maternal OGTT glucose concentrations at 26 30 gestational weeks (online Figure 1).
7 Our overall objective was to determine which factors occurring during the antenatal period and first six months of life were associated with infant growth (length-for-age z scores) at 6 months of age, and to clarify whether associations were direct, or indirectly mediated via infant birth weight.
