Correlation of salivary immunoglobulin A with Body Mass Index and fat percentage in overweight/obese children

Abstract: Obesity is considered a risk factor for periodontal health due to the low- grade inflammation promoted by the increased adipose tissue. Objective: This study aimed to determine correlations and associations between gingival inflammation (Simplified Oral Hygiene Index, and Gingival Index), salivary immunoglobulin A (s-IgA), and salivary parameters (salivary flow and osmolality) in normal-weight and overweight/obese children. Material and Methods: Ninety-one children, aged 6 to 12 years old (8.6±1.9 years), were… Show more

“…Pandey et al observed that immunoglobulin A (IgA‐s), which binds to different molecular components and interferes with microbial adhesion, is predominant in saliva and is an important part in caries prevention process. A previous study showed that overweight/obese children have higher levels of saliva IgA‐s . Given the above, it is reasonable to infer that OW children have fewer chances to develop dental caries because their saliva contains higher levels of IgA‐s.…”

“…The review included 12 cross-sectional studies [ [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] , [37] , [38] , [39] ] and three prospective cohort studies [ [40] , [41] , [42] ]. The included studies were conducted in 10 countries: Brazil [ 33 , 36 , 40 ], Sweden [ 32 , 34 , 38 ], the United States [ 30 , 35 ], Canada [ 31 ], China [ 39 ], Kuwait [ 42 ], Poland [ 37 ], Saudi Arabia [ 28 ], Switzerland [ 41 ], and Turkey [ 29 ]. Except for two studies that did not provide information on the sex of the participants [ 28 , 39 ], all remaining studies included children and adolescents of both sexes.…”

“…There were also significantly higher salivary concentrations of IL-6, TNF-α, insulin, and MCP-1 (monocyte chemoattractant protein-1) in these patients. The leptin concentration was also directly proportional to the insulin concentration [39]. Furthermore Perez et al demonstrated that the concentration of salivary IgA (s-IgA) is significantly higher in the group of overweight and obese children than in the group of normal weight children, reaching the highest concentration among obese children (p < 0.05) having body fat content expressed as percentage of total body composition (p < 0.05) [40].…”
