Africa’s urban poor becoming obese

Yeah, you read that right. Overweight and obesity in urban Africa: A problem of the rich or the poor?: Descriptive results showed that the prevalence of urban overweight/obesity increased by nearly 35% during the period covered. The increase was higher among the poorest (+50%) than among the richest (+7%). Importantly, there was an increase of…

Seems to be the upshot of this finding, I’ll Have What She’s Having: Effects of Social Influence and Body Type on the Food Choices of Others: This research examines how the body type of consumers affects the food consumption of other consumers around them. We find that consumers anchor on the quantities others around them…

Obesity & ancestry in African Americans

Another study on obesity & Africans, with a slight twist, Admixture Mapping of Obesity-related Traits in African Americans: The Atherosclerosis Risk in Communities (ARIC) Study: Obesity is an important cause of morbidity and mortality worldwide. In the United States, the prevalence of obesity is higher in African Americans than whites, even after adjustment for socioeconomic…

Common body mass index-associated variants confer risk of extreme obesity: To investigate the genetic architecture of severe obesity, we performed a genome-wide association study of 775 cases and 3197 unascertained controls at 550 000 markers across the autosomal genome. We found convincing association to the previously described locus including the FTO gene. We also found…

Disease & democracy

Fat Tax: Which is why it is so striking to talk to Delos M. Cosgrove, the heart surgeon who is the clinic’s chief executive, about the initiative. Cosgrove says that if it were up to him, if there weren’t legal issues, he would not only stop hiring smokers. He would also stop hiring obese people.…

FTO, weight, and the mouse

A very thorough paper in PLoS Genetics on the “obesity gene,” FTO, A Mouse Model for the Metabolic Effects of the Human Fat Mass and Obesity Associated FTO Gene: Geneticists have identified many gene regions that cause human disease by using multiple genetic markers in large populations to find gene regions associated with disease. However,…

Heritability of height vs. weight

Megan McArdle has a post, Thining Thin, a follow up to America’s Moral Panic Over Obesity. She says: 1. Obesity is increasing in the population, so it can’t be genetic. Well, average height is also increasing in the population. Does that mean that you could be as tall as me, if you weren’t too lazy…

Tyler Cowen linked to a Time article on the phenomenon of Southern Americans being relatively overweight vis-a-vis Americans from other regions of the country. Several reasons are offered, from the lower per capita income of Southern states, to the fact that Southern food tends to be fried and less healthful. But the article doesn’t mention…

Why we’re fat

Derek Thompson at The Atlantic passes on this awesome chart: OK, OK, obesity is more complex than that. But check out The Big Max: Using New York’s calorie-disclosure regulation to get the most for your money.

Fat and tuberculosis

Obesity May Have Offered Edge Over TB: Over the course of human evolution, people with excess stores of fat have been more likely to survive famines, many scientists believe, living on to pass their genes to the next generation. But these days, obesity is thought to be harmful, leading to chronic inflammation and metabolic disorders…
