When the mother is slimming, the children become slimming

Overweight and obesity go back in families. The relationship can be genetic but also with family relationships and lifestyle habits.

– Parents have a major impact on children's health and lifestyle. A behavior that obesity is easily transferred from the parents to the children, "says Marit Næss.

She is a laboratory director at the dog research center and doctorate student in NTNU.

But how do your lifestyle changes affect the young man body mass index (BMI)? Næss and colleagues have been investigated using numbers of dogs, the Health Survey in Nord-Trøndelag.

It turns out that the parents 'lifestyle affects the children' They are very different depending on whether they are mom or dad we are talking about.

Dad's slimming medium is small

If your mother loses weight, it also affects the children.

"If Mom is down to two or six kilograms, this can be linked to lower BMI in children," says Kirsty Lohmann, researcher in the dog, the Health Survey in Nord-Trendelag.

The researchers found no significant connection if father loses weight, although it may be possible to read a tendency in the same direction.

The results of the recent study of similar studies in India and Finland, but the fines found that the greatest father also affected the weight of their daughters.

The differences between the meaning of father and mother's lifestyle changes do not end up with him.

Less active, bigger children

"Mothers who get low activity levels over the years through childhood adolescence can be linked to children with higher BMI in youth," says Næss.

If the mother does not stay physically active, the children become even bigger. Also, the fatal choice has no significant meaning. More inactive fathers can not be linked to higher education in the children.

Many suggest that Mom is still the one who is primarily responsible for planning to do in the world and perhaps diet, speculative næs and qualities, although this has not been invested this time.

Perhaps it's too often about the mother wanting to lose weight. It makes small changes in diet and living habits that involve the entire family.

This is reinforced by the fact that there is no corresponding relationship, where the parents go very much in balance. This type of weight change can often be associated with illness or more extensive diets that do not involve more in the family.

Education also plays a role

The results are quite clear and also applicable when taking into account the education level.

"BMI is an average lower in families with high education compared to low-education families," explains Kvaløy.

However, weight reduction techniques might seem more effective in the children's BMI in families with higher education.

The study includes 4424 children and parents who have reported a major health survey in Nord-Trendelag. Researchers have followed changes in weight and physical activity over 11 years. A positive change is that, in average, people have become more active in recent years.
