I have no idea how cuts in the NHS has any baring on children’s height. Poor diet certainly has a baring on children’s growth. And in the years since the 1980s what has happened to food in the UK? A proliferation of fast food outlets, mainly imported from America. McDonald, Burger King, Pizza Hut, Kentucky Fried Chicken, and the list goes on. All food from these places is c…p. No vegetables, no salad, no fruit, few vitamins, but high in salts, sugars, and fats. This is what is causing children not to grow as tall as they once did. Many parents can’t or won’t cook, or because they’re working, have little time to cook. Children are given what they will eat with little preparation. Frozen pizza, frozen chips, ready meals etc. Nothing to do with the NHS and everything to do with poor diet.
Add to that Dutch and Scandinavian children have always been bigger than British children, whilst Italian and Greek children have always been smaller.
Add that poor diet of pregnant mothers and smoking of pregnant mothers and children will be smaller. Not that I think being a centimetre and a half is much to worry about. So long as the children are not fat. That is certainly something to worry about.
