{"title":"Reviewing the Chinese-Specific Reference Amounts Study Conducted by Sun et al., 2022.","authors":"W Marty Blom, Joost Westerhout, Geert F Houben","doi":"10.46234/ccdcw2023.145","DOIUrl":"https://doi.org/10.46234/ccdcw2023.145","url":null,"abstract":"The need for region-specific food intake values to accurately estimate food allergen risk is underscored by the recent Ad Hoc Joint Food and Agriculture Organization/World Health Organization (FAO/ WHO) Expert Consultation on Risk Assessment of Food Allergens (1). A recent study published by Sun et al. in China CDC Weekly 2022, titled A ChineseSpecific Reference Amounts Study with TNO Food Allergen Risk Assessment Models — China, 2022, critically examines and applies a previously established sensitivity analysis aimed at deriving food intake values for food allergen risk assessment (RA) (2–3). In their examination of Chinese food consumption data, the authors find that “the 95th–99th percentiles of the food consumption distribution per eating occasion for condiments and chocolates are the optimal point estimates for use in deterministic allergen RA, aiming to protect 99% of allergic individuals from allergic reactions due to unintended peanut presence.” This finding significantly deviates from those of Blom et al., which suggested that the 50th–75th percentiles of the food consumption distribution per eating occasion in various global contexts would suffice for achieving a similar safety objective aimed at protecting 95%–99% of allergic individuals from objective allergic reactions due to unintended allergen presence (3–4). While a more cautious approach to consumption estimations may appear safe from a risk management perspective, such an approach could involve a degree of overprotection that may result in unwarranted restrictions for both the Chinese food-allergic population and the food industry. Achieving a balance between guaranteeing safety and implementing realistic, pragmatic protocols is vital (1). Thus, a risk assessment that incorporates unnecessary high-intake figures may not provide risk managers with the most effective information(5). Hence, we evaluated the potential causes of the elevated P-values discovered in the study by Sun et al. (2). We focused on identifying elements that could significantly augment the sensitivity analysis, ultimately leading to the establishment of a more robust food intake estimation for China. Several factors in the data utilized by Sun et al. (2) could be contributing to the observed elevated P-values (Table 1), thus likely resulting in an excessively conservative outcome, more so than what was projected when the sensitivity analysis method was initially applied. For instance, the food consumption distribution employed in the study lacks the necessary diversity in comparison to the food consumption distribution from other research, thereby contributing to a less refined point estimate (Table 2). A striking similarity can be seen between the consumption ranges of condiments in China and the Netherlands, hovering between 25 grams to approximately 250 grams within the 50th and 99th percentile of the intake distribution (Table 2).

As restrictions associated with the epidemic are relaxed and a fresh policy cycle commences, China’s economy is expected to serve as a key driver of global economic postpandemic recovery. For over four and a half decades, China has witnessed rapid economic growth, positioning itself as the world’s second-largest economy. Notably, from 2012 to 2022, the gross domestic product (GDP) of China expanded more than twofold, from 53.9 trillion Chinese yuan (CNY) [approximately 7.58 trillion United States dollars (USD)] to 121.02 trillion CNY (17.93 trillion USD). In the same period, the country had an average annual GDP growth rate of 6.2%, one of the highest globally (2). Alongside this economic growth, China also achieved significant strides in environmental conservation. Specifically, energy consumption per unit of GDP reduced by 8.1%, and CO2 emissions decreased by 14.1%. Furthermore, from 2018 to 2022, an improvement was observed in water quality in cities at or above the prefectural level, with the percentage of good-quality surface water bodies increasing from 67.9% to 87.9%. Air quality also improved, with the average particulate matter 2.5 (PM2.5) concentration decreasing by 27.5% and severe air pollution days declining by over 50% (2). However, simultaneous industrial expansion and rapid urbanization, coupled with an increase in energy consumption and a burgeoning vehicular population, have amplified environmental pollution issues. This situation presents a significant challenge to both socioeconomic development and public health in China, reflecting environmental health challenges often encountered by developing nations.","PeriodicalId":9867,"journal":{"name":"China CDC Weekly","volume":"5 32","pages":"715-719"},"PeriodicalIF":0.0,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/58/fe/ccdcw-5-32-715.PMC10442698.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10122696","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
