NDNS: Time trend and income analyses for Years 1 to 9 

The latest report was released on 23 January 2019. Below is the summary of results:

  • Fruit and vegetable intake has remained low, with mean intakes for all groups being below the 5 a day recommendation. 
  • There was a decline observed in the intake over time of the amount of fruit juice consumed, however the proportion of individuals consuming juice showed little change.
  • Over the 9-year period there was little difference in the intakes of oily-fish, however a decline over time was observed for red and processed meat consumption.
  • There was a reduction observed in the proportion of children consuming sugar-sweetened soft drinks in all age groups. For those children who drank sugar-sweetened soft drinks, intake amount also fell significantly over time.
  • Taking income into account there was evidence of a greater fruit and vegetable intakes with increasing income in all age/sex groups except men aged 65 years and over and higher percentages of consumers of fruit juice and oily fish with increasing income. A downward trend with increasing household income was observed for the percentage consuming sugar-sweetened soft drinks for all age/sex groups except boys aged 11-18 years and adults aged 65 years and over.
  • Free sugars intake in children significantly decreased over the 9 years. A reduction was also seen in adults as a percentage of total energy over time, although to a smaller extent than in children. Average intakes still exceeded current recommendations in all age/sex groups over the whole 9 years.
  • No trend over time was observed for total fat or saturated fatty acid intakes as a percentage of food energy. Average intakes of saturated fatty acids exceeded current recommendation over the 9-year period.
  • A small decrease over time was observed in AOAC fibre intake in all child age/sex groups, but this was only significant for children aged 4 to 10 years. A significant increase was observed in men aged 19 to 64 years. Average intakes in all age/sex groups over the 9 years remained well below current recommendations.
  • There was a downward trend in intakes of most vitamins and minerals over the 9-year period for many age/sex groups.
  • There was a significant decrease over time in sodium intake in all age/sex groups.
  • Average folate intake for most age/sex groups remained above the RNI over the 9 years, however the average intake for girls aged 11 to 18 years dropped and remained below the RNI. For girls aged 11 to 18 years and women aged 19 to 64 years, the proportion with intakes below the Lower Reference Nutrient Intake (LRNI) increased by 9 and 6 percentage points respectively over the 9-year period. 
  • Blood folate concentrations also decreased significantly over the 9 years for most age/sex groups, and the proportion of participants with folate concentrations indicating risk of anaemia increased. Time-trend analysis of the proportion of women of childbearing age (16 to 49 years) with a red blood cell folate concentration below the threshold for increased risk of neural tube defects-affected pregnancies (748nmol/L), indicates an overall increase from approximately two thirds to almost 90% over the 9 years.
