Prevalence of starving people worldwide 2022, by region

In 2022, the rate of undernourishment worldwide was 9.2 percent. The region with the largest share of undernourished people was Sub-Saharan Africa, with 22.5 percent. Undernourished people worldwideSouthern Asia and Sub-Saharan Africa have some of the highest numbers of undernourished people in the world, totaling 314 million and 262 million, respectively in 2022. Based on the World Hunger Index 2022, Yemen and the Central African Republic were among the most affected countries by hunger and malnutrition. Worldwide, there were about 735 million people suffering from malnutrition in 2022. MalnutritionMalnourishment occurs when a person’s diet consists of too little or too much of certain nutrients. Undernutrition occurs when a person does not intake enough calories, protein, or micronutrients. One of the primary causes of malnutrition is due to limited or lack of accessibility to affordable nutritious foods. Malnutrition is considered to contribute to over a third of child deaths globally. In Asia, an estimated 77 million cases of stunting, which is the primary effect of malnutrition, were recorded for children under the age of five in 2022. The FAO reports that food security and nutrition commitments by national governments are essential in eradicating the world hunger problem. Agricultural productivity, accessibility to land, service, and markets, rural development strategies, and social protection are needed to ensure a reduction in malnutrition.

于2022年，全球营养不良率达到了9.2%。在所有地区中，撒哈拉以南非洲所承担的饥饿人口比例最高，达到了22.5%。全球范围内，南亚和撒哈拉以南非洲地区承载着世界上最多的营养不良人口，分别达到了3.14亿和2.62亿。根据2022年世界饥饿指数，也门和中非共和国是受饥饿和营养不良影响最为严重的国家之一。在全球范围内，2022年约有7.35亿人遭受营养不良之苦。营养不良现象发生时，个体的饮食中缺乏或过量某些营养素。当一个人摄入的热量、蛋白质或微量营养素不足时，即发生营养不良。营养不良的主要成因之一是有限的或缺乏获取经济实惠且营养丰富的食品的途径。营养不良被视为导致全球儿童死亡超过三分之一的原因。在亚洲，2022年记录了约7700万例生长迟缓病例，这是营养不良的主要效应，涉及五岁以下儿童。根据联合国粮食及农业组织（FAO）的报告，各国政府在粮食安全和营养方面的承诺对于消除世界饥饿问题至关重要。提高农业生产力、土地、服务和市场的可及性、乡村发展战略以及社会保障措施是确保营养不良率降低的必要条件。
