Abstract

There is an emerging body of studies showing the association of snacking behaviour with weight status or nutritional status in general populations (1, 2). However, there is a lacking of evidence examining the link of snacking frequency with nutritional status in urban-living professional workers. This study investigated the association of daily snacking frequency with nutritional status amongst professional workers residing in the North West of England.
35 professional workers (M 13, F 22) aged 30-65 years old were recruited via random selection from Liverpool and its surrounding areas. Laboratory and anthropometric measures of CVD risk were assessed including blood pressure, measures of central obesity and biomarkers of fasting capillary blood glucose and lipid profile. Dietary intake profiles including total energy, nutrients and snacking behaviours were recorded using a validated 3-day diet diary and analysed using a dietary assessment software Microdiet. Information on working hours per week was collected using a sociodemographic questionnaire. Variation in nutritional status amongst all snacking-frequency groups was assessed by Univariate analysis with Bonferroni post hoc test using SPSS (v 22). The statistical significance was set at ≤ 0.05.
The snack items consumed comprised hot and cold beverages, wine and beer, savoury snacks, fruit and vegetables, toast, sandwich, crumpet, humus, bread sticks, cereals, cereal bars, dairy foods, sweets, confectioneries, ice cream, nuts, raisins, fruit jelly and yogurt. Significant variations existed in age, working hours/week and dietary nutritional profiles across all snack-frequency groups. In conclusion, total energy and certain macronutrient intakes followed an increasing trend with the increased snacking frequencies. Snacking of four times a day resulted in significantly higher intakes of vitamin B2 and B5 compared to the snacking of twice a day group but stayed the lowest in the total carotene intake. Snacking of the highest frequency was observed in the youngest age group who worked for almost the shortest working time per week amongst all.
