To validate a Tanner stages self-assessment questionnaire using gender-specific line drawings and brief explanatory text in Chinese.
A cross sectional study design.
One primary and two secondary schools.
172 boys and 182 girls aged between 8 and 18 years.
Students' self-assessments of pubertal maturation were compared with assessments made by a same gender rater using visual depiction physical examination. Raters' physical examinations were performed after the children had answered the self-assessment questionnaire individually and in private. Raters were blinded to the self-assessment results. Accuracy rates and weighted kappa statistic were used to evaluate the degree of agreement between children and raters.
Substantial to almost perfect agreement was found between self- and rater's assessments of breast development and pubic hair growth in girls [weighted kappa 0.72 (P < 0.0001, 95% CI 0.66, 0.79) and 0.83 (P < 0.0001, 95% CI 0.78, 0.87) respectively]. Moderate to substantial agreement was found between self- and rater's assessments of male genital development and pubic hair growth [weighted kappa 0.58 (P < 0.0001, 95% CI 0.48, 0.68) and 0.80 (P < 0.0001, 95% CI 0.74, 0.86) respectively]. Most agreements between self- and rater's assessments differed by only one Tanner stage. Agreement was higher for girls than boys. Girls tended to overestimate their breast stages and boys tended to underestimate their genitalia development.
This study confirms that a Tanner pubertal self-assessment questionnaire with line drawings and explanatory Chinese text can reliably estimate sexual maturation status in Hong Kong Chinese children.
使用特定性别的线条图和中文简短解释性文本验证坦纳分期自我评估问卷。
横断面研究设计。
一所小学和两所中学。
172名年龄在8至18岁之间的男孩和182名女孩。
将学生对青春期成熟度的自我评估与使用视觉描述体格检查的同性评估者的评估进行比较。在孩子们单独且私下回答自我评估问卷后，评估者进行体格检查。评估者对自我评估结果不知情。准确率和加权kappa统计量用于评估儿童与评估者之间的一致程度。
女孩自我评估与评估者对乳房发育和阴毛生长的评估之间存在高度到几乎完美的一致性[加权kappa分别为0.72（P<0.0001，95%CI 0.66，0.79）和0.83（P<0.0001，95%CI 0.78，0.87）]。男孩自我评估与评估者对男性生殖器发育和阴毛生长的评估之间存在中度到高度的一致性[加权kappa分别为0.58（P<0.0001，95%CI 0.48，0.68）和0.80（P<0.0001，95%CI 0.74，0.86）]。自我评估与评估者评估之间的大多数一致性仅相差一个坦纳分期。女孩的一致性高于男孩。女孩往往高估自己的乳房分期，男孩往往低估自己的生殖器发育。
本研究证实，带有线条图和中文解释文本的坦纳青春期自我评估问卷能够可靠地估计香港华裔儿童的性成熟状况。
