Protocol for an interventional study to reduce postpartum weight retention in obese mothers using the internet of things and a mobile application: a randomized controlled trial (SpringMom).

Background: Obese pregnant women are known to experience poorer pregnancy outcomes and are at higher risk of postnatal arteriosclerosis. Hence, weight control during and after pregnancy is important for reducing these risks. The objective of our planned randomized controlled trial is to evaluate whether the rate of change in body weight in obese women before pregnancy to 12 months postpartum would be lower with the use of an intervention consisting of Internet of Things (IoT) devices and mobile applications during pregnancy to 1 year postpartum compared to a non-intervention group.

Male Infants Born to Older Pregnant Women Are Affected by Maternal Physique at the Beginning of the Pregnancy through Birth until 18 Months of Age.

We have previously reported a positive correlation between the body mass index (BMI) of mothers and the Kaup index of infants at birth and that this correlation may have a stronger influence on the male infants, born to older mothers. Therefore, in this study, we aimed to clarify the correlation between maternal age and gender of the infants as maternal BMI and the Kaup index of infants from birth till 18 mo of age. This study was conducted from April 2010 to September 2011 in Japan.

Maternal Body Mass Index Correlates with the Neonatal Physique of Male Infants.

Recently, in Japan, the percentage of leanness has risen in young women, and the average birth weight has decreased. An increase in the risk of low birth weight has been reported in lean expectant mothers. In this study, we aimed to clarify the relationship between mother's physique at the beginning of pregnancy and the infant's physique, by focusing on sex differences.

Relationship between physique and food avoidance in infants: a study conducted in a community setting in Japan.

The relationship between food avoidance during infancy and the growth of Japanese infants in a community health setting has not been well evaluated. In order to assess the growth of infants who avoided either of the three major allergen foods in Japan, eggs, milk or wheat, we employed the results of 4 physical checkups recorded in maternity passbooks and administrated a questionnaire on allergic diseases, height and weight at birth to the guardians of 1,132 infants at the age of 3.5 years.
