To clarify the correlation between the Japanese Aging Male Questionnaire (JAMQ) and the Aging Males' Symptoms (AMS) scale through the factor analysis in Japanese male.
In 61 male patients who visited the LOH outpatient clinic of Teikyo University Hospital, subjective symptoms featuring LOH were evaluated using the JAMQ and AMS. Factor analysis was performed on each questionnaire to clarify the LOH-related factors. Correlational analysis between the subscale scores representing such factors and the serum hormone profiles was also performed.
Factor analysis of the JAMQ revealed an internal structure consisting of three subgroups: somatic, psychological and sexual factors with good categorization of the indicators to the appropriate subgroup. In contrast, the indicators of the AMS showed incomplete conformity to the subgroups of the JAMQ. Correlational analysis showed that each score on the JAMQ subgroups had the highest coefficient of correlation with the corresponding AMS subgroup (p < 0.001). There was no significant association between total and free serum testosterone levels and the total and subscale scores on either AMS or JAMQ.
The results of factor analysis suggest that the sexual perceptions of Japanese populations might differ from those of Caucasian populations. JAMQ would be useful to separately assess individual aspects of somatic, psychological and sexual symptoms related to LOH among Japanese males.
通过对日本男性进行因子分析，明确日本男性老龄化问卷（JAMQ）与老龄化男性症状（AMS）量表之间的相关性。
在 61 名因男性中老年健康问题（LOH）就诊于帝京大学医院 LOH 门诊的男性患者中，使用 JAMQ 和 AMS 评估 LOH 的主观症状。对每个问卷进行因子分析，以明确与 LOH 相关的因素。还对代表这些因素的子量表评分与血清激素谱之间的相关性进行了分析。
JAMQ 的因子分析显示，其内部结构由躯体、心理和性三个亚组组成，指标对适当的亚组有较好的分类。相比之下，AMS 的指标与 JAMQ 的亚组不完全一致。相关性分析表明，JAMQ 亚组的每个评分与相应的 AMS 亚组的相关性最高（p<0.001）。总睾酮和游离睾酮水平与 AMS 或 JAMQ 的总分和子量表评分均无显著相关性。
因子分析的结果表明，日本人群的性认知可能与白种人群不同。JAMQ 可用于分别评估日本男性与 LOH 相关的躯体、心理和性症状的各个方面。
