Characteristics of published cross-sectional studies outlining the relationship between body mass index (BMI) and dental caries in Adults residing in KSA.
| Author(s) | City/Region | Setting | Sample Size | Age (y) | Caries Parameter | Low BMI | High BMI | Outcome |
|---|---|---|---|---|---|---|---|---|
| Alswat et al. (2016)# | Taif | Outpatient (University Clinic) | 385 | 28.4 ± 11.4 | DMFT | U = 5.26 | OW = 6.42 O = 6.48 |
Overweight and obese patients had a non-statistically significant dental caries in comparison to the normal weight patients (P = 0.29) |
| Ashour et al. (2019)## | Taif | Inpatient (Mental Hospital) | 223 | 42.3 ± 2.2 | DMFT | U = 2.6 ± 1.6 | OW = 5.2 ± 4.7 O = 4.1 ± 3.6 |
There is a strong association between dental caries and increased BMI (Adjusted odds ratio = 2.7; 95% CI = 1.4–4.3; P < 0.001) |
| Hamasha et al. (2019)### | Riyadh | Outpatient (Dental Clinic) | 250 | 35.3 | DMFT | U = 12 | OW = 14 O = 16 |
Patients with higher BMI were more likely to have increased dental caries (P = 0.005) |
| Idrees et al. (2017) | Riyadh | Outpatient (Dental Hospital) | 502 | M – 26.5 ± 4.8 (38.2%) F – 22.8 ± 4.5 (61.8%) |
DMFT | U = 14.0 ± 3.8 | OW = 13.8 ± 3.1 O = 12.9 ± 4.4 |
There was no correlation between BMI and dental caries (P = 0.15). |
