The effects of various parameters on age at menopause have been investigated in five ethnic groups in Israel comprising East European, West European, North African, Israeli and other Middle Eastern (Mediterranean) women, respectively. The data were acquired by means of anonymous questionnaires and were programmed for 1770 women. Correlation coefficients between various variables and age at menopause revealed three variables which have a straight correlation, vis. obesity index, number of children, and years of amenorrhoea (during the reproductive years). The years-of-smoking variable has an inverse correlation with age at menopause. East Europeans have the highest age at menarche. Two-way analysis of variance has shown that the obesity index, years of amenorrhoea, number of children and years-of-smoking parameters are individually more important than ethnic origin. The finding that the age at menopause is highest in the North African group is explained by the higher incidence in this group of high parity, a greater number of amenorrhoea, obesity, and low cigarette consumption. Since many habits (such as smoking, diet, use of contraceptive pills, multiple partners and marital obligations) are subject to frequent change in the modern world, it is of the utmost importance to repeat such a study every few years.
在以色列的五个族群中，分别对东欧、西欧、北非、以色列及其他中东（地中海地区）女性的各种参数对绝经年龄的影响进行了调查。数据通过匿名问卷收集，并针对1770名女性进行了编程处理。各种变量与绝经年龄之间的相关系数显示有三个变量呈直接相关，即肥胖指数、子女数量和闭经年限（在生育期内）。吸烟年限变量与绝经年龄呈负相关。东欧女性初潮年龄最高。双向方差分析表明，肥胖指数、闭经年限、子女数量和吸烟年限参数各自比种族起源更为重要。北非人群绝经年龄最高这一发现可通过该群体中高生育胎次、更多闭经、肥胖及低吸烟量的更高发生率来解释。由于现代社会中许多习惯（如吸烟、饮食、避孕药使用、多个性伴侣及婚姻义务等）经常发生变化，每隔几年重复进行这样的研究至关重要。
