Cephalic index is an important parameter for differentiation of race and sex which varies significantly on the basis of hereditary, geographical, racial, sexual and other factors. It is a morphometric expression of different forms of head. The objective of this research was to evaluate the cephalic index of people of indigenous Tharu community of Biratnagar, Nepal and to determine different head types.
A cross-sectional study was conducted in which maximum head length and breadth of 100 adult Tharu people living in Biratnagar were measured using spreading caliper and scale. The cephalic index was obtained from these values using Hrdlicka's method.
The mean cephalic index of the study population was 75.99±4.97. The mean cephalic indices of males and females were 76.22±5.14 and 75.78±4.85 respectively. The most common head type observed was dolichocephalic type 47 (47%). It was followed by mesocephalic type 37 (37%), brachycephalic type 13 (13%) was less common and least common was hyperbrachycephalic type 3 (3%).
Long head (dolichocephalic) type is more common in Tharu population in both the genders, whereas, broad head (brachycephalic and hyperbrachycephalic) type is present in very few people.
头指数是区分种族和性别的一个重要参数，它会因遗传、地理、种族、性别和其他因素而有显著差异。它是不同头型的一种形态测量表达。本研究的目的是评估尼泊尔比拉特纳格尔土著塔鲁社区人群的头指数，并确定不同的头型。
进行了一项横断面研究，使用游标卡尺和直尺测量了居住在比拉特纳格尔的100名成年塔鲁人的最大头长和头宽。使用赫德利卡方法从这些值中获得头指数。
研究人群的平均头指数为75.99±4.97。男性和女性的平均头指数分别为76.22±5.14和75.78±4.85。观察到最常见的头型是长头型，有47人（47%）。其次是中头型，有37人（37%），短头型13人（13%）较不常见，超短头型3人（3%）最不常见。
在塔鲁人群中，长头（长头型）在男女中都更为常见，而宽头（短头型和超短头型）的人很少。
