Background: Clinical diagnosis of human dysmorphology is relied on physical examination and phenotypic characterization. However, the evaluation of adult dysmorphology is limited since most standard reference studied population of specific ethnic groups that may be not applied to Thai population.

Methods: Standard physical measurement was performed in Thai medical students and medical trainees at the age of 20 - 35 years. Past medical history was screened by face-to-face interview to exclude an individual with chronic illness. Hence, the recruited subjects were assumed to represent healthy population. The measurement procedure was based on standard technique worldwide include height, body mass index, several craniofacial and limb parameters.

Results: Total 186 individuals (96 males and 90 females) were recruited for this study. The mean sge was 27.20 ± 2.90 years (male 26.92 ± 2.88, female 27.53 ± 2.85). Physical measurement data was defined as mean ± standard deviation in males and females, respectively. The height was 174.60 ± 5.10 and 160.15 ± 4.67 cm. The head circumference was 57.47 ± 1.36 and 54.73 ± 1.45 cm. Facial length (forehead to chin) was 17.56 ± 1.07 and 16.13 ± 1.02 cm. Intercanthal distance was 3.43 ± 0.28 and 3.29 ± 0.26 cm. Interpupillary distance was 6.47 ± 0.31 and 6.17 ± 0.33 cm. Ear length was 6.59 ± 0.40 and 6.09 ± 0.35 cm. Mouth length was 5.28 ± 0.48 and 4.97 ± 0.47 cm. Middle finger length was 8.21 ± 0.39 and 7.54 ± 0.43 cm. Palm length was 11.18 ± 0.57 and 10.09 ± 0.49 cm. Sole length was 23.68 ± 1.14 and 21.37 ± 1.10 cm. Centile charts were constructed for future clinical use.

Conclusions: These physical parameters represent the normal variation of adult healthy individuals. This information is a useful reference for diagnosis of adult dysmorphology in Thai ethnic group.
