Skewed sex ratios indicative of a greater preponderance of males over females (approximating 4:1) has perhaps been the most constant collective finding in autism spectrum conditions. More recent investigations have indicated a potential change to traditional estimates of gender ratios. We undertook analysis to calculate contemporaneous gender ratios based on collective and individual sub-diagnoses. A sample of 1963 children diagnosed with autism (n = 460), Asperger syndrome (n = 366) or autism spectrum disorder (ASD) (n = 1137) were included for study. The overall gender ratio based on a year of birth between 1986–2007 was 7.38:1. Differences were found amongst the sub-diagnoses for the same period (autism = 6.54:1, Asperger syndrome = 12.07:1; ASD = 6.84:1). Analysis of annual trends indicated an irregular upwards tendency to gender ratios indicative of increasing over-representation of males with an autism spectrum condition despite no indication of greater disparity in population sex ratios at birth. Further independent studies are required to corroborate our findings.

I recommend highly Clinical Medicine Insights: Endocrinology and Diabetes as it provides guidance in each step of the publication process. The peer review was also in high quality yet very constructive.
All authors are surveyed after their articles are published. Authors are asked to rate their experience in a variety of areas, and their responses help us to monitor our performance. Presented here are their responses in some key areas. No 'poor' or 'very poor' responses were received; these are represented in the 'other' category.See Our Results
