Major Findings
Yuan et al., [36]
China
To investigate gender and age as moderators in the association between
BMI and mild cognitive impairment (MCI) among rural older adults
Cross-sectional Aged 60 and above (Range from 60 to 100 )
Age scategorised into
Below 75 and above 75 .
n = 3242 BMI
[sCategorised into underweight (low BMI), normal weight (normal BMI), overweight (elevated BMI) and obese (high BMI)]
MMSE
(30 Items; Chinese Version)
Below 75 years (Both men and women)
There was no significant difference in MCI among overweight and obese categories when compared to normal BMI. (p>0.05)
Above 75 years.
Older men
Compared to nomal BMI category, Overweight category had higher risk of MCI (aOR = 2.32, 95 % CI: 1.17–4.61; p<0.05)
Older women
BMI (overweight and Obesity) vs. MCI – NS
Salama et al., [37]
Egypt
To assess MCI prevalence and its relation with lifestyle
risk factors among obese adults
Case-control Mean age case (Obese) – 52.1± 5
Mean age control (Healthy) – 51.3± 6
Case (Obesity) n=161
Control (Healthy) n=69
BMI
Obesity Gr. I (BMI <35)
Obesity Gr. II (BMI 35-39.9)
Obesity Gr. III (BMI>40)
ACE (Version III) MCI was assessed between Obesity categories (I, II and III) and control (healthy adults)
MCI between Grade I and Control (OR – 5.5, 95 % CI: 2.2-13.5; p<0.001)
MCI between Grade II and Control (OR – 6.8, 95 % CI: 2.7-16.9; p<0.001)
MCI between Grade III and Control (OR – 4.8, 95 % CI: 1.8-12.5; p<0.001)
