Leaving school and getting a job both lead to a drop in the amount of physical activity and may lead to an unhealthy lifestyle, while becoming a mother is linked to increased weight gain, researchers have found.

Many people tend to put on weight as they leave adolescence and move into adulthood and this is the age when the levels of obesity increase the fastest, the study said.

This weight gain is related to changes in diet and physical activity behaviour across the life events of early adulthood, including the move from school to further education and employment, starting new relationships and having children.

“This evidence suggests that the pressures of university, employment and childcare drive changes in behaviour which are likely to be bad for long-term health,” said study researcher Eleanor Winpenny from University of Cambridge in the US.

For the study, published in the journal Obesity Reviews, researchers looked at changes in physical activity, diet and body weight as young adults move from education into employment and to becoming a parent.

To do this, they carried out systematic reviews and meta-analyses of existing scientific literature.

In the first of the two studies, the research team looked at the evidence relating to the transition from high school into higher education or employment and how this affects body weight, diet and physical activity.

In total, they found 19 studies covering ages 15-35 years, of which 17 assessed changes in physical activity, three body weight, and five diet or eating behaviours.

The team found that leaving high school was associated with a decrease of seven minutes per day of moderate-to-vigorous physical activity.

The decrease was larger for males than it was for females (a decrease of 16.4 minutes per day for men compared to 6.7 minutes per day for women).

More detailed analysis revealed that the change is largest when people go to university, with overall levels of moderate-to-vigorous physical activity falling by 11.4 minutes per day.

In the second study, the team looked at the impact of becoming a parent on weight, diet and physical activity.

A meta-analysis of six studies found the difference in change in body mass index (BMI) between remaining without children and becoming a parent was 17 per cent: a woman of average height (164 cm) who had no children gained around 7.5 kg over five to six years, while a mother of the same height would gain an additional 1.3 kg.

These equate to increases in BMI of 2.8 versus 3.3. According to the researchers, most studies including physical activity showed a greater decline in parents versus non-parents.

The research team found limited evidence for diet, which did not seem to differ between parents and non-parents. (IANS)

Young Mothers are More Prone To Have Mental Health Problems: Study

Almost 40 per cent of young moms have more than one mental health issue, including depression, a range of anxiety disorders and hyperactivity

Researchers have found that two out of three young mothers have at least one mental health issue.

The study, published in the Journal of Adolescent Health, found that teen mothers have a much higher prevalence of mental health challenges than mothers aged 21 and older and teens who aren’t parents.

Almost 40 per cent of young moms have more than one mental health issue, including depression, a range of anxiety disorders and hyperactivity.

This is up to four times higher than in mothers aged 21 years or older and teens without children, the researchers said,

“Now that we understand that young mothers can struggle with problems other than just postpartum depression, our findings can be used to develop better screening processes, more effectively detect mental health problems in teenaged mothers, and direct treatment,” said study researcher Ryan Van Lieshout from McMaster University in Canada.

For the findings, Between 2012 and 2015, the Young Mothers Health Study recruited 450 mothers aged younger than 21 years old and 100 comparison mothers aged older than 20 years old at the time of their first delivery. The moms were from Hamilton, Niagara, Haldimand-Norfolk, and Brant counties.

This study is the one of the first in the world to use diagnostic interviews to examine a range of mental health problems beyond postpartum depression.

“Structured diagnostic interviews are the gold standard for this kind of research. We’re glad to have used this method to talk to hundreds of young mothers about their experiences,” said study lead author Van Lieshout.

Age-matched young mothers were also compared with 15 to 17-year-old women without children from the 2014 Ontario Child Health Study who were assessed for mental disorders, the researchers said.

The study said identifying and treating mental health issues in young mothers is especially important as their health also affects the wellbeing of their children.

“Young mothers can face a great deal of adversity both before and after becoming a parent, yet next-to-nothing has been known about the rates and types of significant mental health problems among these women in our community,” Lieshout said. (IANS)
