Changes In Frequency Of Consumption Research Articles

Association between hourly wages and dietary intake after the first phase of implementation of the Minneapolis minimum wage ordinance.

In 2018, Minneapolis began phased implementation of an ordinance to increase the local minimum wage to $15/h. We sought to determine whether the first phase of implementation was associated with changes in frequency of consumption of fruits and vegetables (F&V), whole-grain-rich foods, and foods high in added sugars among low-wage workers. Natural experiment. The Wages Study is a prospective cohort study of 974 low-wage workers followed throughout the phased implementation of the ordinance (2018-2022). We used difference-in-difference analysis to compare outcomes among workers in Minneapolis, Minnesota, to those in a comparison city (Raleigh, North Carolina). We assessed wages using participants' pay stubs and dietary intake using the National Cancer Institute Dietary Screener Questionnaire. Analyses use the first two waves of Wages data (2018 (baseline), 2019) and includes 267 and 336 low-wage workers in Minneapolis and Raleigh, respectively. After the first phase of implementation, wages increased in both cities, but the increase was $0·84 greater in Minneapolis (P = 0·02). However, the first phase of the policy's implementation was not associated with changes in daily frequency of consumption of F&V (IRR = 1·03, 95 % CI: 0·86, 1·24, P = 0·73), whole-grain-rich foods (IRR = 1·23, 95 % CI: 0·89, 1·70, P = 0·20), or foods high in added sugars (IRR = 1·13, 95 % CI: 0·86, 1·47, P = 0·38) among workers in Minneapolis compared to Raleigh. The first phase of implementation of the Minneapolis minimum wage policy was associated with increased wages, but not with changes in dietary intake. Future research should examine whether full implementation is associated dietary changes.

The Longitudinal Associations between Perceived Descriptive Peer Norms and Eating and Drinking Behavior: An Initial Examination in Young Adults.

Experimental and cross-sectional studies indicate that perceptions of the eating and drinking behavior of one's peers (perceived descriptive peer norms) are associated with the types, frequency and quantity of food, and beverages a person chooses to consume. At present, we know very little about the longitudinal association between perceived descriptive peer norms and future eating or drinking behavior. In this study, we examined whether perceived descriptive peer norms for different food/beverage types predicted frequency of consumption of food/beverages in university students. Three hundred and forty participants completed measures at baseline and follow-up for frequency of consumption of cakes/pastries, sugar containing beverages, and alcoholic beverages, as well as measures of perceived descriptive peer norms at both time points. Perceived descriptive peer norms predicted consumption of pastries/cakes at follow up when controlling for changes in these perceptions over time; believing that one's peers frequently consumed cakes/pastries was associated with an increased frequency of consumption over time, although the magnitude of this effect was small. There was no significant association between perceived descriptive peer norms and changes in frequency of consumption of sugar containing beverages or alcohol over time. In the present longitudinal study of young adults, beliefs about how often one's peers eat or drink specific food and beverages types had limited effect on future eating and drinking behavior.

Frequency of consumption, familiarity and preferences for chestnuts in Missouri

A study of frequency of consumption and familiarity with preparing chestnuts was conducted in the state of Missouri from 2003 to 2008. A conjoint analysis of chestnut attributes was completed in 2008 to expand on previous consumer preference research. Information from final consumers was collected during the annual Missouri Chestnut Roast festival at the Horticulture and Agroforestry Research Center in New Franklin, Missouri. The study tracks changes in frequency of consumption and consumer familiarity with preparing chestnuts. The conjoint analysis evaluated pair-wise profiles to quantify the effects of origin, production process and price on consumer preferences. Results show improvements in the frequency of consumption and familiarity with cooking chestnuts in Missouri. Findings suggest the festival has influenced consumption patterns among return visitors. The conjoint analysis identified locality of produce and organic certification to be major drivers behind consumer preferences. Price is also an important attribute influencing consumer preferences. Conjoint analysis results indicate that chestnuts grown in Missouri or the U.S. carrying an organic label can capture price premiums.

Changes in Diet During Adult Life and Risk of Colorectal Adenomas

: To evaluate the associations of changes in diet during adult life with adenoma risk, data from a case-control study of 146 colorectal adenomas and 226 controls were analyzed. Dietary habits during the year before sigmoidoscopy and when subjects were 30 yr old were collected using a food-frequency questionnaire. Change in frequency of consumption during adulthood was calculated by subtracting frequency of consumption of specific foods or food groups at age 30 yr from frequency of consumption during the previous year (recent consumption). Associations with changes in frequency of consumption were estimated by odds ratios (ORs) and 95% confidence intervals (CIs). There was no association for foods or food groups consumed at age 30 yr. For recent consumption, more frequent consumption of red meat, breakfast sausage, and pork chops/ham steaks and less frequent consumption of fish, chicken/turkey, and vegetables were related to a higher risk. Compared with individuals with the highest reduction in consumption since age 30 yr, risks were higher for those with smallest reduction in red meat intake (OR = 2.8; CI = 1.1-7.3), particularly for hamburgers/cheeseburgers (OR = 2.8; CI = 1.2-6.8) and pork chops/ham steaks (OR = 3.7; CI = 1.6-8.7). In contrast, individuals in the highest quartile of increased consumption of fish (OR = 0.6; CI = 0.3-1.1) and vegetables (OR = 0.5; CI = 0.3-1.1) had a lower risk compared with those with minimal increase in consumption. In conclusion, irrespective of frequency of consumption at age 30 yr, a greater reduction in consumption of red meat and a larger increase in consumption of vegetables since age 30 yr were associated with a decreased risk of colorectal adenomas later in life.

Dietary and Physical Activity Correlates of Long‐Term Weight Loss

Covariations in body mass index (BMI), physical activity, macronutrient intake, and the frequency of consumption of specific foods were examined among 82 men and 75 women participating in a behavioral weight loss program over a period of 18 months. Results of repeated measures analyses of covariance showed that BMI change was inversely related to change in physical activity and change in frequency of vegetable consumption. BMI change was positively related to change in calorie intake from fat and change in frequency of consumption of beef, hot dogs, and sweets. Change in fat calories predicted BMI change better than change in total calories. In addition, change in the frequency of consumption of specific foods accounted for a larger percentage of the variance in BMI change than did change in macronutrients (10.4% vs. 5.2%). No differences were found between predictors of weight loss vs. weight maintenance.

Reproducibility of a self-administered questionnaire for dietary habits, smoking, and drinking

Reproducibility of results from a self-administered questionnaire on dietary habits (the frequency of taking various foods and eating habits), smoking and drinking was examined to study the reliability of the questionnaire, stability of lifestyle, and the validity of the questionnaire in assessing lifestyle as a risk factor in chronic diseases. The study sample included 120 males and 173 females in a rural town in Kyoto Prefecture, who participated in a series of three health examinations in 1988, 1989, and 1992. A survey using the same questionnaire was performed before each health examination. Reproducibility was assessed by correlation (Spearman's rank correlation coefficient or kappa coefficient), exact agreement of category answered, and comparison of mean frequency. An attempt was made to separate reliability and stability from reproducibility using the data from the questionnaire obtained in the three years. Good reproducibility for one-year and four-year intervals was found for foods taken habitually or often (boiled rice, cooked rice gruel with tea, milk, coffee, fruits and bread), and habits (eating breakfast, some eating habits, smoking and drinking). The same was also found for cigarette or alcohol consumption among current consumers except that cigarette consumption over a four-year interval was more likely to change. The reliability of the questionnaire and stability of these items were considered satisfactory, suggesting that the questionnaire was a valid method of assessing long-term lifestyle. Poor reproducibility of results regarding consumption of green-yellow and other vegetables indicated both poor reliability and a change in consumption over four years, and suggested poor validity. However, disagreement in more than one category of vegetables was not large and misclassification in assessing them as risk factors and changes in frequency of consumption may not be large either. Although correlation coefficients for the items of dairy food and eating snacks were fair, disagreement in more than one category was relatively large which may have caused misclassification. The mean frequency of consumption of pickles and fishpaste, ham or sausage significantly decreased over the four year interval. This may reflect the influence of health education on reducing salt intake.

Influence of cravings and aversions on diet in pregnancy

Using interviews at specific periods during pregnancy, this study examined the influence of maternal dietary cravings and aversions during pregnancy on frequency of consumption of dietary items, among a sample of 400 white, well‐nourished women in Albany, New York, whose pregnancies were ascertained by the 13th week. Seventy‐six percent of the women reported craving at least one item, while 85% reported at least one aversion. The greatest changes in frequency of consumption, according to 7‐day diet histories, occurred between the last menstrual period and the 12th week. Most cravings and aversions also occurred early, with aversions earlier than cravings. A decrease in mean frequency of consumption of craved items was noted for only two foods (vegetables and ice cream) out of a total of 18. Women reporting aversions showed a similar pattern of change, an increase in consumption for two of 18 items (white milk and fruit). Thus, women reporting cravings generally increased their consumption of food items cr...
