What was the obesity rate in 1980

This explanation also accounts for the strong class gradient of obesity, with the poor having much higher levels than more economically secure groups. And this explanation also explains why the rates of obesity in the U. Obviously, something as complex as obesity prevalence has many causal factors, and the weakness of public transportation and the corresponding heavy use of cars in transport no doubt is another factor, but economic insecurity is very probably a part of the solution.

By the way, the study cited below appears to support this explanation. Finally, thanks for your excellent blog. Obesity under affluence varies by welfare regimes: The effect of fast food, insecurity, and inequality Original Research Article. Think before you respond, Barnes.

Richard: Very glad to hear about your successful weight loss. The top line is still rising as the overall average weight goes up. People need to learn to cook again. A few years ago, at 32, I finally learned how to really cook. I lost 40 pounds. And now I am teaching my mother so that she can help my father lose weight for the sake of his heart. For 40 years the main option for vegetables she gave him was steamed, which really do need to be choked down trust me.

The 26 percent increase in hours worked mainly reflects increases in work outside of the home among women. In fact, among two-parent families with median earnings, the hours of men were relatively constant over time, while hours worked by women more than doubled from to If you look at the chart in this link that details the increased hours worked by the average American family, you will see it correlates almost exactly with the calorie and obesity charts in this topic. Another omitted variable could be sleep.

Think about professional discus throwers in track and field or bodybuilders. Professor, how familiar are you with the work on activity levels? Much of it is unreliable: small studies, short time periods, data taken out of the original study context. For example, the activity study that says levels have not decreased had to search literature and only found for North America subjects across 13 studies which had been designed to test other things.

The authors note they had a lot of problems with the data. BTW, their other main data was a short study done in one Dutch town. Another example is pedometer studies. If you look into them, you see they tend to cover few people for short periods.

And there are only a few of them. The numbers have been widely quoted but there is little foundation in them. I mean, bluntly, they discuss how being fat increases energy output just to move around a bit and so I expect they include that factor. Your basic premise in this post is that obesity is a supply function. The implication you draw is the demand function generates extra fat, which is also true, but may be misleading.

Have you really thought through the demand side of this function? Just as physicians advise us that even 20 minutes of walking or other light to moderate per day is sufficient for cardiovascular health and for substantial longevity benefits, perhaps reducing physical activity beyond some threshold or inflection point leads to outsized detriment in terms of body weight and health. Clearly, the increase in caloric intake has a lot and maybe everything to do with rising obesity.

But I would not discount inactivity as being a major factor without more evidence than looking at graphs for direct correlation. If you want to know the true source of obesity focus on corn which is found in everything. That one ingredient—high fructose corn syrup—is the culprit.

Look at the list of ingredients on any cereal box, guaranteed you will find it there. Therefore, for a family of four, a PIR of 1. Statistical significance was assessed in logistic regression models that included PIR and age as continuous variables.

If the goal is to reduce poverty and create opportunities for advancement, then building grocery stores in the inner city should be evaluated against other antipoverty strategies, like increasing income transfers, workforce development services, and improved preschool and early learning opportunities alongside higher-education funding.

Indeed, attending and finishing college is highly correlated with lower obesity levels and better health and life outcomes across the board. In fact, some research suggests that higher education is not just correlative of lower obesity risk, but also causally improves the odds of having a healthy body weight.

Similarly, increasing long-term access to high-quality health care for low-income individuals will likely improve health outcomes more than banning soda vending machines and ending agricultural subsidies. Effective therapies for heart disease, hypertension, and diabetes have already weakened the relationship between obesity and mortality for Americans who can afford them. Extending better health treatments to a wider spectrum of the public would not only be a victory for public health, it would also help low-income individuals in broader ways than more-targeted investments aimed at improving food and activity environments can.

Every dollar invested in improving health care access to reduce diabetes and hypertension can also help reduce other poor health outcomes that afflict low-income people with little access to health care, including many that have little to do with obesity or dietary habits. All this should challenge the application of the antismoking model to obesity.

Where smoking can be banned, overeating cannot be. The two behaviors are similar only in that they, like much else we do, are factors in health.

There is no secondhand eating. Overeating and unhealthy foods are fuzzily, subjectively, and variously defined, whereas we can all agree on what smoking and cigarettes are.

What that means is that unhealthy foods will remain widely available — even more available than cigarettes, which can still be found at any corner store. If history is any guide, food availability and diversity are likely to increase, not decrease.

The focus on food environments also led school-based efforts themselves to be too limited. The past decade has seen growing evidence that things like self-control, character, and emotional self-regulation can be taught, and some educators are exploring ways to integrate these techniques more fully into the classroom.

As such, nutrition education and school gardening programs are probably a lot less valuable than curriculums that show young people how to manage desires for unhealthy foods. It will impact their behavior at home, on the streets, and eventually at the workplace, where they will make the decisions that shape not just their bodies but also their lives.

Today, the criticism applies to the public health establishment itself. In place of a narrow focus on diet, we should concentrate on a broader set of factors. Breslow, Lester. William L.

Diets are different than they were 30 years ago, and modern technology has decreased physical activity.

Developing countries now have a lot of the conveniences that are commonplace in wealthier nations. Sturchio said that blood pressure and cholesterol medications are difficult to get in developing countries, also contributing to the rise in obesity. Countries that have experienced conflict or natural disaster may rely on prepared foods that often contain high levels of salt, which contributes to high blood pressure," he said.

Changing views of obesity could also be contributing to the pandemic while also reducing high blood pressure and cholesterol levels. Stress has been strongly linked to high blood pressure and cholesterol.
