Obe­sity in preg­nancy brings risk of di­a­betes

The China Post - - INTERNATIONAL -

Women who are obese while preg­nant may put their off­spring at risk of child­hood di­a­betes, a con­di­tion that re­quires life­long in­sulin ther­apy, Swedish re­searchers said Tues­day.

A study of more than 1.2 mil­lion chil­dren born in Swe­den be­tween 1992 and 2004 and mon­i­tored for sev­eral years, found a 33-per­cent higher risk for the dis­ease among chil­dren whose moth­ers were obese dur­ing the first trimester of preg­nancy, but were not di­a­betic them­selves.

“Ma­ter­nal over­weight and obe­sity in early preg­nancy were as­so­ci­ated with in­creased risk of type 1 di­a­betes in the off­spring of par­ents with­out di­a­betes,” a team wrote in Di­a­betolo­gia, the jour­nal of the Euro­pean As­so­ci­a­tion for the Study of Di­a­betes.

The high­est risk was still for chil­dren of par­ents who had di­a­betes them­selves, the study found. There was no ad­di­tional risk for chil­dren of moth­ers who were obese on top of hav­ing di­a­betes.

Over 5,700 chil­dren from the study group were di­ag­nosed with type 1 di­a­betes by 2009.

Type 1 di­a­betes is

usu­ally found in chil­dren and young peo­ple — a chronic con­di­tion caused when the pan­creas does not pro­duce in­sulin to con­trol blood sugar lev­els. It re­quires life­long in­sulin treat­ment, and con­sti­tutes about 10 per­cent of all di­a­betes cases — though the num­ber is grow­ing.

And the in­crease “may partly be ex­plained by in­creas­ing preva­lence of ma­ter­nal over­weight/ obe­sity,” said the study.

Peo­ple with a BMI (body weight in­dex, a ra­tio of weight to height) of 25 and higher are clas­si­fied over­weight, and 30 and over obese.

Obe­sity, too, is soar­ing, hav­ing more than dou­bled world­wide since 1980. By 2014, more than 1.9 bil­lion adults were over­weight, of whom 600 mil­lion were obese, ac­cord­ing to the World Health Or­ga­ni­za­tion.

Type 2 di­a­betes is much more com­mon than type 1, and is be­lieved to be caused by life­style fac­tors, and con­trolled through healthy diet, ex­er­cise and med­i­ca­tion.

“Pre­ven­tion of over­weight and obe­sity in women of re­pro­duc­tive age may con­trib­ute to a de­creased in­ci­dence of type 1 di­a­betes,” the study con­cluded.
