Mumbai: Kids and young adults in the city are not getting enough exposure to sunlight, resulting in high levels of Vitamin D deficiency, according to a recent study.
The study by PD Hinduja Hospital found that Mumbaikars are shunning even half an hour of exposure to the sun in a day, considered ideal worldwide. Vitamin D is secreted in the body when the skin is sufficiently exposed to sunlight.
Dr Vipla Puri, consultant (radioimmunoassay), at the hospital’s department of lab-medicine said, “The decline in Vitamin D levels indicates that kids have sedentary lifestyles — watching television, playing indoor games or using computers.” She said most children and young adults in the study belonged to the higher socio-economic strata. “Vitamin D deficiency has reached alarming proportions and parents must take steps to alter their kids’ lifestyle if they want to protect them from serious diseases,” said Puri.
Pediatrician Dr Deepak Urga, who consults with Lilavati Hospital, termed Vitamin D deficiency in children as an “alarming problem”. “Children are increasingly getting used to a life without natural light,” he said. Blaming food habits, Ugra said the kind of food children in metros prefer are not rich sources of Vitamin D. “It gets tougher for vegetarians as Vitamin D sources are sparse,” he said.
Studies show it affects the immune system in children. “Vitamin D deficiency causes allergies and respiratory infections in children,” said Ugra. He added most vitamin supplements also fail to provide the quota of anything between 200-1000 IU/ day (international unit).
Physician Dr Pratik Samdani alsoblamed pollution. “Factorslike latitude, atmospheric pollution, duration and time of exposure to sunlight is also important for the skin to absorb and use it,” he said.
