6.mature mums
Mothers around the world are getting older.in the UK,the mean age for aving a frist child is 27.3,compared with 23.7 in 1970 .mean age at frist birth in the US has also increased, rising from 21.4 in 1970 to 24.9 in 2000.
This would be neither here nor there if it were’t for the observation that having an older mother seems to be an independent risk factor for obesity. Results from the US national heart,lung and blood institute’s study found that the odds of a child being obese increase 14% for every five extra years of their mother’s age , though why this should be so is not entirely clear.
Michael Symonds at the university of Nottingham,UK,found that first-bron children have more fat than younger ones. As family size decreases, firstbrons account for a greather share of the population. In 1964, british women gave birth to an average of 2.95 children;by 2005 that figure had fallen to 1.79. in the US in 1976, 9.6% of woman in their 40s had only one chile;in 2004 it was 17.4%. this combination of older mothers and more single children could be contributing to the obesity epidemic.
