To identify lifestyle, socioeconomic, and metabolic factors associated with tooth loss among community-dwelling middle-aged and elderly men.
Enrolled 8,352 men aged 40 to 79 years undergoing annual health checkups in northern Japan between 2002 and 2005.
Categorized participants by self-reported remaining teeth into two groups (≤19 teeth vs. ≥20 teeth).
Evaluated independent risk factors for retaining 19 or fewer teeth using multivariate logistic regression.
Among all participants, 21.1% (n=1,764) had 0 teeth, 21.3% (n=1,779) had 1 to 9 teeth, 22.0% (n=1,836) had 10 to 19 teeth, and 35.6% (n=2,973) retained 20 or more teeth.
Having 19 or fewer teeth significantly associated with older age, past or current smoking, lower education, lower body mass index, lower serum albumin, and non-drinking status.
In middle-aged men (40 to 64 years), having 19 or fewer teeth was additionally linked to lower HDL cholesterol and elevated glycosylated hemoglobin (HbA1c).
