“…Participants reported spending ¥14.05 on food and non-tap water beverages during every 24-hour observationperiod, while spending¥19.14 per 2000 kcal, which were similar to the estimated mean expenditures on food at home (¥19.99/2000kcal) based on retail prices on the Nantong city of China [24] , and were similar to the cost of school-aged children in Southwest China (¥11.0/1000kal) [14] . The differences between several socio-demographic characteristics and daily diet cost or daily energyadjusted diet costwere explored.…”

“…While the associations linking dietary cost and diet quality remain mostly unexplored in Chinese, except forone study discussed among school-aged children [14] .Generally, Chinese dietary patterns and diet-related behaviors have undergone a signi cant transition in the past few decades, trending towards diversi cation and modernization [15] . Therefore, there is a need for improvement in diet quality for the Chinese adults.…”

Objectives: Food price is a determining factor in food choices. However, its relationship with diet quality is unclear in Chinese adults. This study aimed to examine daily energy-adjusted dietary cost (Chinese Yuan, CNY/2000kcal) concerning diet quality in northeast central Chinese adults. Methods: The food consumed by 680 Chinese adults from Henan province during the year 2020 was recorded by 24-h dietary recalls. Three dietary quality indices, namely the nutrient-rich foods (NRF) index, the mean adequacy ratio (MAR), and the energy density (ED), were adopted. Daily energy-adjusted diet cost was calculated by dividing the estimated daily diet costs (CNY/day) by the energy intake per day (kcal/day) and multiplying 2000. Results: Subjects who closely adhered to the NRF9.2, MAR, and ED paid daily ¥8.92, ¥13.17, and ¥14.34 more for food consumption, respectively, than those who weakly adhered to these dietary patterns. Furthermore, adjusted linear regression analysis revealed that an increase in ¥1 of the energy-adjusted diet cost per day was associated with a change of 0.494 units (P< 0.001), 0.003 units (P<0.001), and -0.018 units (P<0.001) in the NRF9.2, MAR, and ED, respectively. Conclusion: Higher energy-adjusted diet costs were associated with higher-quality diets. This might be of importance for public health policies in an effort to develop strategies to promote healthy diets by regulating food and diet costs.

“…Meanwhile, a study in Cambodia showed that a better diet was associated with a reduction in stunting [31]. Studies in Chinese children showed that better diet quality was negatively associated with the prevalence of stunting, anemia (hemoglobin level < 110 g/L for children under 5 years old, <115 g/L for children aged 5-11, and <120 g/L for children aged 12-14 [35]), and obesity [36,37]. Moreover, improving diet quality was also shown to reduce autism disorder symptoms (which were characterized by lack of social interaction, deficits in language/communication, and routine repetitive behaviors) in preschoolers in Hong Kong, China [38].…”

This study aims to examine the relationship between diet quality and health outcomes among children in rural remote areas of China. We draw on a cross-sectional dataset of 1216 children from two counties in the Gansu Province in Northwest China. Child health outcomes were assessed with both anthropometric measurements and reports by primary caregivers of the children. Child diet quality was assessed with the diet quality score (DQS) using information from a food frequency questionnaire (FFQ). Our data show the prevalence of stunting and underweight among sample children were 12% and 11%, respectively; 27% of children were reported by their caregivers as unhealthy, and 60% of children had at least one of the seventeen selected non-communicable diseases (NCDs) over the past 14 days. Overall, 780 (72%) children have at least one of the four above-mentioned health problems. Results from logistic regression models show that a higher DQS was significantly associated with a lower likelihood of being stunted and a higher likelihood of being reported healthy after adjusting for confounders. These findings imply that improving child diet quality might be an option when designing interventions to improve child health.

“…Finally, none of the included studies examined the pathway from convenience store accessibility to childhood obesity through unhealthy dietary behaviors. Accessibility only represents availability and is not equal to affordability or acceptability, not to mention children–convenience store interaction in the real world 64,65 . Therefore, future research should test the validity of measures of exposure to food environments, such as children's journeys through the food environment, as well as food purchasing and consumption behaviors, which will aid in effective control of childhood overweight and obesity through, for example, school food policies and interventions 66 …”

Summary Childhood obesity increases the risk of adulthood obesity and is associated with other adverse health outcomes later in life. It may be influenced by environmental characteristics of neighborhoods where children live, particularly dietary supply–related environmental factors. This study aimed to systematically review the evidence on the association between access to convenience stores and childhood obesity. We searched and filtered relevant literature in PubMed, Embase, Web of Science, and Cochrane Library published before 1 January 2019. Data on the basic characteristics of studies, measures of access to convenience stores, and associations of convenience stores with weight‐related behaviors and outcomes were extracted from 41 included studies. In general, the density of and proximity to convenience stores in children's residential and school neighborhoods were positively associated with unhealthy eating behaviors. However, their associations with children's weight status varied significantly by regions. The association between convenience store access and children's weight status was found to be negative in Canada, rather mixed in the United States and the United Kingdom, and not significant in East Asia. We suggest future research to clearly define the convenience store, better measure the access to convenience store, and also measure children's journey and food purchasing and consumption behaviors, to explain pathways from convenience store access to childhood obesity for designing effective interventions and policies.
