Study: Normalization of ‘Plus-Size’ Risks Hidden Danger of Obesity

The normalization of “plus-size” body shapes may be leading to an increasing number of people underestimating their weight — undermining efforts to tackle England’s ever-growing obesity problem, according to an academic at the University of East Anglia. While attempts to reduce stigmatization of larger body sizes — for example, with the launch of plus-size clothing ranges — help promote body positivity, the study highlights an unintentional negative consequence that may prevent recognition of the health risks of being overweight.

The study by Dr. Raya Muttarak, from the University of East Anglia (UEA) and the International Institute for Applied Systems Analysis (IIASA) in Austria, examined the demographic and socioeconomic characteristics associated with underestimation of weight status to reveal social inequalities in patterns of weight misperception.

Analysis of data from almost 23,460 people who are overweight or obese revealed that weight misperception has increased in England. Men and individuals with lower education and income levels are more likely to underestimate their weight status and, consequently, less likely to try to lose weight.

Men and individuals with lower levels of education and income are more likely to underestimate their weight status, especially regarding obesity, and are consequently less likely to try to lose weight.

Members of minority ethnic groups are also more likely to underestimate their weight than the white population. However, they are more likely to try to lose weight. Those underestimating their weight are 85 percent less likely to try to lose weight than people who accurately identified their weight status.

Global growing obesity rates

The results, published in the journal Obesity, show that overweight individuals misperceiving their weight has increased over time, from 48.4 percent to 57.9 percent in men and 24.5 percent to 30.6 percent in women between 1997 and 2015. Similarly, among individuals classified as obese, the proportion of men misperceiving their weight in 2015 was almost double that of 1997 (12 percent vs. 6.6 percent).

The study comes amid growing global concern about rising obesity rates. It follows a 2017 report by the Organization for Economic Co-operation and Development (OECD) that showed 63 percent of adults in the UK are overweight or obese. Dr. Muttarak, a senior lecturer in UEA’s School of International Development, says her findings have important implications for public health policies:

“Seeing the huge potential of the fuller-sized fashion market, retailers may have contributed to the normalisation of being overweight and obese.

“While this type of body positive movement helps reduce stigmatisation of larger-sized bodies, it can potentially undermine the recognition of being overweight and its health consequences. The increase in weight misperception in England is alarming and possibly a result of this normalisation.

Dr. Muttarak added:

The study used data from the annual Health Survey for England, which contains a question on weight perception. Focusing on respondents with a BMI of 25 or over, about two-thirds were classified as being overweight and one-third as obese. The analysis was based on pooled data from five years — 1997, 1998, 2002, 2014, and 2015 — to assess trends in self-perception of weight status.

The proportion underestimating their weight status was higher among overweight individuals compared with those with obesity (40.8 percent vs. 8.4 percent). Correspondingly, only about half of overweight individuals were trying to lose weight compared with more than two-thirds of people with obesity.
