The seasonal variation of the suicides (n = 57,007) that occurred in Italy during the years 1969-1984 was evaluated using harmonic analysis, according to the method described by Pocock (1974). Monthly data were analyzed, separately for males and females, taking into account the setting (urban or rural) and the geographical location (Northern, Central or Southern regions). As compared with a previous study by our research group, a more precise (less aggregated) index of the urban-rural continuum was used. Rates for males were greater than those for females; urban were higher than rural rates; the seasonality was greater in the rural than in the urban settings and generally greater in males than in females in the Southern as well as in the Northern regions.
根据波科克（1974年）描述的方法，采用调和分析评估了1969年至1984年期间在意大利发生的自杀事件（n = 57,007）的季节性变化。分析了月度数据，按性别分别进行，并考虑了环境（城市或农村）和地理位置（北部、中部或南部地区）。与我们研究小组之前的一项研究相比，使用了更精确（聚合程度更低）的城乡连续体指数。男性的自杀率高于女性；城市地区的自杀率高于农村地区；农村地区的季节性高于城市地区，并且在南部和北部地区，男性的季节性一般都高于女性。
