Change in hyper-palatable food availability in the US food system over 30 years: 1988-2018.

OBJECTIVE: To quantify the change in availability of hyper-palatable foods (HPF) in the US foods system over 30 years (1988-2018). DESIGN: Three datasets considered representative of the US food system were used in analyses to represent years 1988, 2001 and 2018. A standardised definition from Fazzino et al. (2019) that specifies combinations of nutrients was used to identify HPF. SETTING: Analysis of food-item level data was conducted. Differences in the prevalence of HPF were characterised by Cochran's Q and McNemar's tests. Generalised linear mixed models with a fixed effect for time and random intercept for food item estimated change in the likelihood that a food was classified as hyper-palatable over time. PARTICIPANTS: No participant data were used. RESULTS: The prevalence of HPF increased 20 % from 1988 to 2018 (from 49 % to 69 %; P < 0·0001). The most prominent difference was in the availability of HPF high in fat and Na, which evidenced a 17 % higher prevalence in 2018 compared with 1988 (P < 0·0001). Compared with 1988, the same food items were >2 times more likely to be hyper-palatable in 2001, and the same food items were >4 times more likely to be classified as hyper-palatable in 2018 compared with 1988 (P values < 0·0001). CONCLUSIONS: The availability of HPF in the US food system increased substantially over 30 years. Existing food products in the food system may have been reformulated over time to enhance their palatability.

A contemporary look at the relationship between general cognitive ability and job performance.

The relationship between general cognitive ability (GCA) and overall job performance has been a long-accepted fact in industrial and organizational psychology. However, the most prominent data on this relationship date back more than 50 years. This meta-analysis examines the relationship between GCA and overall job performance using studies from the current century. Results across 153 samples and a total sample size of 40,740 show a mean observed validity of .16, with a residual SD of .09. Correcting for unreliability in the criterion and correcting predictive studies for range restriction produces a mean corrected validity of .22 and a residual SD of .11. While this is a much smaller estimate than the .51 value offered by Schmidt and Hunter (1998), that value has been critiqued by Sackett et al. (2022), who offered a mean corrected validity of .31 based on integrating findings from prior meta-analyses of 20th century data. We obtain a lower value (.22) for 21st century data. We conclude that GCA is related to job performance, but our estimate of the magnitude of the relationship is lower than prior estimates. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
