Optimising nutrition and consumption for better health: An analysis of noncommunicable disease strategies in the organisation for economic co‐operation and development nations

The role of nutrition in promoting health and reducing the prevalence of noncommunicable diseases (NCDs) is vital, yet both inadequate and excessive food consumption can be detrimental. Moreover, excessive smoking and alcohol consumption contribute to higher mortality rates. Countries have implemented policies, strategies, and awareness campaigns to combat NCD‐related deaths. Within this context, the study aims to assess the relative efficiency of Organisation for Economic Co‐operation and Development (OECD) countries in preventing chronic NCDs by considering nutritional supply and smoking and alcohol consumption as inputs. It also seeks to identify countries' best policies and strategies to reduce regular NCD‐related death rates, emphasizing the importance of selecting and implementing adaptive strategies locally. This study employs slack‐based measurement (SBM) data envelopment analysis (SBM‐DEA). The mean efficiency score across the countries is 0.95, with a standard deviation of 0.09, indicating a generally high‐efficiency level. Twenty‐nine countries with an efficiency score of 1 are deemed relatively efficient. Austria, Belgium, Germany, Greece, Ireland, Korea, Luxembourg, the United Kingdom, and the United States did not achieve relative efficiency in NCD management. The findings highlight the importance of considering the unique context of each country when designing and implementing NCD prevention and management strategies. The study emphasizes the need for regular evaluation and appropriate measurement methods to assess the achievement of targets and address implementation challenges. Furthermore, it highlights the significance of adopting a comprehensive, coordinated approach to ensure the effectiveness of NCD policies and underscores the need for flexibility and adaptability in addressing NCDs.
