Examining Association Between Reported High Cholesterol and Risk Factors in Adults With Intellectual and Developmental Disabilities (IDD): A Five-Year Follow-Up.

Murthy et al. (2021) · Intellectual and developmental disabilities 2021
★ The Verdict

Obesity plus diabetes forecasts cholesterol trouble in adults with ID—screen early and move more.

01Research in Context

01

What this study did

The team tracked the adults with intellectual or developmental disabilities for five years.

They asked: do obesity and diabetes predict who later reports high cholesterol?

Data came from yearly medical charts and staff reports, not lab tests.

02

What they found

Both obesity and diabetes raised the odds of reported high cholesterol.

Diabetes also carried part of obesity’s effect, acting like a middleman.

In plain words, extra weight matters, but diabetes makes it matter more.

03

How this fits with other research

Hastings et al. (2002) saw fewer heart-risk reports in older adults with ID, hinting doctors may miss the signs; Sumithra’s longer watch finds the risks are real once you track them.

Diaz (2020) adds a life-saving footnote: leisure walking lowers death risk in the same group, so the obesity found here is actionable.

Pan et al. (2016) saw a large share of students with ID already overweight, sounding an early alarm that matches the adult pattern Sumithra shows.

The papers don’t clash—kids, adults, and elders all point to the same weight-health link.

04

Why it matters

You now have a five-year signal: clients who are both obese and diabetic need cholesterol checks even if they feel fine. Build two habits into care plans: routine blood work and daily 10-minute walks with staff. These simple moves can catch risk early and may extend life, as Diaz (2020) suggests.

03Original abstract

Adults with intellectual and developmental disabilities (IDD) are at a greater risk of developing high cholesterol and cardiovascular disease. We examined whether physical inactivity, obesity, and diabetes were predictive of reported high cholesterol and whether there were any mediating effects of diabetes on the relationship between obesity and high cholesterol in 1,618 adults with IDD across five years. Results suggest that obesity and diabetes were significantly associated with high cholesterol after adjusting for age, sex, and residence type with a partial mediator effect of diabetes in the relationship between obesity and high cholesterol across all time points. Further research is needed to explore the causal mechanisms behind the relationships between obesity, diabetes, and high cholesterol.
