What was a key outcome of the 1920s health reforms?

The choice regarding expanded urban sanitation and healthcare accessibility is the correct answer because the health reforms of the 1920s focused significantly on improving public health systems in response to the challenges posed by rapid urbanization and the aftermath of World War I. During this period, governments recognized the necessity of providing better sanitation and healthcare services to address the health crises exacerbated by overcrowded cities and inadequate public health infrastructures.

The introduction of initiatives such as public health campaigns, the establishment of health committees, and investment in sanitation infrastructure contributed to noticeable improvements in urban health conditions. Clean water supply systems, sewage disposal, and waste management were prioritized, which significantly decreased the prevalence of diseases linked to poor sanitary conditions.

In contrast, the other options do not accurately reflect the outcomes of the reforms. Conditions did not worsen; rather, they improved due to enhanced health policies. Additionally, there was a focus on training and employing more medical personnel rather than reducing training, and while infectious diseases remained a challenge, the reforms aimed to curtail their spread through better public health measures.
