Young Adults in Poor Neighborhoods at Greater Risk for Obesity

Healthy-weight young adults who live in neighborhoods with lower education or income levels may be at greater risk of becoming overweight or obese, according to a new study by researchers at Kaiser Permanente.

The findings show that over a four-year period, 25 percent of healthy 18-year-old participants living in disadvantaged areas had become overweight or obese.

“Emerging adulthood is a critical time period for excess weight gain due to a variety of factors, including many teenagers leaving home for college and having more freedom and access to food,” said Deborah Rohm Young, Ph.D., study senior author and director of behavioral research, Kaiser Permanente Southern California, Department of Research & Evaluation.

“Our study found that living in a disadvantaged place puts teens at an increased risk for being overweight or obese. Although we did not explore potential reasons for this increase, factors may include cultural norms, as well as lack of access to public parks and grocery stores.”

In the past three decades, obesity has more than doubled in children and quadrupled in adolescents, with more than one-third of children and adolescents found to be overweight or obese in 2012, according to the Centers for Disease Control and Prevention (CDC).

Social determinants of health, which are the conditions in the environments in which people are born, live, learn, work, play, worship, and age, affect a wide range of health, functioning, and quality-of-life outcomes and risks.

The researchers analyzed the electronic health records of 22,823 racially/ethnically diverse Kaiser Permanente members in Southern California who were 18 years old in 2008 and followed them for four years. They looked at the independent effects of gender, race/ethnicity, and neighborhood-level education and income on incidence of overweight and obesity.

The study’s definition of overweight and obesity was based on the sex-specific body mass index-for-age growth charts developed by the CDC. All of the subjects, with the exception of those who were Asian and Pacific Islanders, were normal weight based on a body mass index (or BMI) less than 25.

Researchers used a lower BMI threshold for Asians — less than 23 — based on recommendations from the World Health Organization, which holds that the increased risks associated with obesity, such as diabetes and hypertension, occur at a lower BMI among this population compared with other racial/ethnic groups.

Over the course of four years, about 23 percent of the normal-weight 18-year-olds living in neighborhoods with low education became overweight and about two percent of those living in lower- income neighborhoods became obese.

Furthermore, females and blacks had almost 1.7 and 1.3 times the increased risk compared with males and whites, respectively, for being overweight or obese. Asians and Pacific Islanders were almost three times more likely to become overweight compared with whites when using a BMI of less than 23.

“This study suggests that a teenager who is currently at a healthy weight can still be at risk of becoming overweight or obese in a short period of time. This seems especially of concern in the presence of a variety of socioeconomic factors,” said Young. “In addition, it is important to use the lower BMI for Asians to ensure we are identifying individuals who may be at risk for obesity and related conditions such as diabetes.”

The findings are published in the journal Pediatric Obesity.
