“…According to previous research in the United States of America (USA) and Europe, some studies reported that the incidence of ALS showed a north to south latitude gradient, i.e. the risk of disease was found to be higher at higher (northerly) latitudes (Annegers et al, 1991). Another study from southern Italy showing a similar gradient supports this finding but does not otherwise explain the small, seemingly uncorrelated variations of ALS incidence in Europe (Logroscino et al, 2005).…”

Abstract. Few studies have assessed the spatial association of amyotrophic lateral sclerosis (ALS) incidence in the world. The aim of this study was to identify the association of climatic factors and ALS incidence in Taiwan. A total of 1,434 subjects with the primary diagnosis of ALS between years 1997 and 2008 were identified in the national health insurance research database. The diagnosis was also verified by the national health insurance programme, which had issued and providing them with "serious disabling disease (SDD) certificates". Local indicators of spatial association were employed to investigate spatial clustering of agestandardised incidence ratios in the townships of the study area. Spatial regression was utilised to reveal any association of annual average climatic factors and ALS incidence for the 12-year study period. The climatic factors included the annual average time of sunlight exposure, average temperature, maximum temperature, minimum temperature, atmospheric pressure, rainfall, relative humidity and wind speed with spatial autocorrelation controlled. Significant correlations were only found for exposure to sunlight and rainfall and it was similar in both genders. The annual average of the former was found to be negatively correlated with ALS, while the latter was positively correlated with ALS incidence. While accepting that ALS is most probably multifactorial, it was concluded that sunlight deprivation and/or rainfall are associated to some degree with ALS incidence in Taiwan.

“…Most studies show incidence and mortality rates in white populations from 1.2 to 4.0 cases per 100 000 persons. [2][3][4]24,25 Only a few studies have examined rates of ALS in minority populations. A population-based study in western Washington State yielded age-adjusted rates of 0.74 for African American men and 0.53 for African American women.…”

“…34,[17][18][19] However, in recent years, the gender gap in ALS incidence rates has appeared to narrow for unknown reasons.8' 10,13,14 A robust association is seen between ALS and increasing age, with peak onset in the 55 to 75 age group.3, 10 ,15,16 As for race, evidence for higher ALS incidence rates in whites compared to non-whites is inconsistent. 15 , 16 Geographic differences, perhaps related to latitude, may correlate with any noted race/ethnicity differences. 15 In addition, population genetics may somehow contribute to geographic variations and also to unexplained spatial clusters of ALS cases.…”
