Considerable attention has been focused on Mexico’s obesity problem (see “Soft drinks, obesity, diabetes and public health in Mexico”). Obesity in adults is defined by the World Health Organization (WHO) as a Body Mass Index (BMI) greater than or equal to 30, where BMI is defined as a person’s weight in kilograms divided by the square of his height in meters (kg/m2).

Mexico’s very high adult obesity rate of 30% is increasing every year. It is related to many factors, including increased consumption of processed fat and sugary foods. The average daily calories consumed by Mexican adults increased from 3102 in 1988 to 3266 in 2007.

Addressing Mexico’s serious obesity problem will require significant effort and dramatic behavioral change, first and foremost by families, but also by schools, government, industry and civic organizations. Most agree that long term solutions for limiting or reducing obesity should focus primary on children and youth. Obviously physical exercise and diet are crucial parts of a solution. Fortunately Mexico is already making efforts to address its child obesity problem (see “Mexico takes on childhood obesity”).

Obesity is quite complicated and may involve numerous heretofore unknown factors. The data are sometimes confusing. For example, Italian adults, with an obesity rate of only 10%, consumed on average a whooping 3646 calories per day in 2007, 380 more than Mexicans, whose obesity rate is three times that of Italy. (The data in this and the next paragraph come from Table 1 of the Milken Institute’s “Waistlines of the World”, August 2012). French adults consume far more calories than Mexican adults, and more fat the US adults, but their obesity rate is much lower, at only 11%. Furthermore, the French consume 50% more alcohol than Americans and almost three times more than Mexicans and yet they are much thinner. Though adults in Norway consume more calories than Mexicans (3169 versus 3102) their obesity rate is only a third that of Mexico (10% versus 30%). Obviously calorie intake is not the only factor and may not be the most important factor.

Mexican Manuel Uribe (1965-2014), one of the world’s most obese individuals, succeeded in lowering his weight from 560 kg (1233 lbs) to 394 kg (867 lbs).

Obesity is also related to amount of physical activity, but here again the data are confusing. New Zealand adults have a high obesity rate of 27% though they live in one of the physically most active countries, with 49% engaging in “moderate physical activity” defined as light-to moderate activity for at least 30 minutes five times per week. On the other hand, only 27% of the relatively thin Italian adults engage in “moderate physical activity”. Why are obesity rates for the more active New Zealanders so much higher than those for the less active Italians, especially since the latter consume 544 more calories per day (3646 versus 3129)? By way of comparison, only 21% of Mexican and 23% of US adults engage in “moderate physical activity”.

How does Mexico’s growing obesity problem compare that of other countries? Data compiled by the World Health Organization (used by Procon.org to compile “US and Global Obesity Levels: The Fat Chart)”) and the OECD in “Waistlines of the World provide a basis for comparing obesity rates in numerous countries (though see note [1] for reservations about using data from different years).

The data indicate that Mexico ranks 12th of 88 countries with an adult obesity rate of 30%, defined as body mass index (BMI) of over 30. While 12th of 88 does not sound so bad, the top six on the list are small island countries with obesity rates from 41% to 79% (Nauru, American Samoa, Tokelau, Tonga, Kiribati and French Polynesia). Also higher than Mexico are the relatively small countries of Panama and the United Arab Emirates. If these small countries are excluded then Mexico ranks 4th among major countries behind only Saudi Arabia, the USA and Egypt (see table).

Mexico trails several notable countries with high obesity rates between 20% and 30% such as Australia, Canada, UK, Chile and South Africa. (Given that obesity rates are increasing almost everywhere and South Africa’s data are from 1998, its current obesity rate is probably closer to 25% or more.)

The global data suggest that the obesity problem is most serious in Pacific Island nations, North America and the Middle East (including North Africa). It is also becoming a problem in several European and Latin American countries. It is less of a problem in Asia and Sub-Sahara Africa.

In conclusion, obesity is a very serious problem for Mexico today, and arguably one of the biggest problems facing humanity in the 21st century along with climate change and poverty.

Note [1]:

There are some significant differences between the WHO and OECD data sets. For example the WHO data for Mexico are from 2000 while the OECD data are from 2006. For our comparisons we use the most recent data available from the two data sets. Though obesity is an extremely important international problem, reliable data is not collected frequently in many countries. Obesity rates are based on measured height and weight, and are invariably higher than rates based on self reported height and weight. In our table, measured values are used for: the USA, Mexico, Australia, Canada, UK, Japan and South Korea; we are not sure about the rates for other countries.

  1. Thats nonsense. The USa is the most obese country but they manipulate the statistics

  2. The most obese countries are actually several small island nations. For more details, see our more recent post, Mexico the fourth most obese country in the world at http://geo-mexico.com/?p=9311
