Table 1

Demographic, clinical and lifestyle characteristics of study participants according to change to a healthy diet after diagnosis of breast cancer

1) Log transformed t-test was used for continuous variables and chi-square test was used for categorical variables.

2) SD: standard deviation

3) Number of participants did not equal to 380 because some participants did not provide the relevent information.

4) AJCC: American Joint Committee on Cancer

5) BMI: body mass index

6) NA: Not available

7) Fisher exact test was used.

Table 2

Adherence score of American Cancer Society (ACS) or World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) guidelines and intake of food groups at interview according to change to a healthy diet after diagnosis of breast cancer (n=380)

1) T-test was used for comparing two groups.

2) SD: standard deviation

3) Among 380, one participant was excluded.

4) Wilcoxon-Mann-Whitney test was used for comparing two groups.

5) Energy dense diet denotes energy intake per amount of total food intake (kcal per 100 g).

Table 3

Odds ratio (OR) and 95% confidence interval (CI) for change to a healthy diet by physical activity and anthropometric measures (n=380)

1) Models were adjusted for age (year; continuous), energy intake (kcal/day; continuous), stage of breast cancer (I, II, III), and alcohol intake (never, former, current).

2) Models were adjusted for age (year; continuous), energy intake (kcal/day; continuous), stage of breast cancer (I, II, III), and alcohol intake (never, former, current). For physical activity, BMI at diagnosis (<23, 23-<25, ≥25 kg/m²) was additionally adjusted. For BMI or weight change, physical activity (MET hours/week, tertile) was additionally adjusted.

3) Models were adjusted for age (year; continuous), energy intake (kcal/day; continuous), stage of breast cancer (I, II, III), and alcohol intake (never, former, current), physical activity (MET hours/week, tertile), and BMI at diagnosis (<23, 23-<25, ≥25 kg/m²).

4) MET: metabolic equivalent task.

5) P for trend was calculated by assigning median or ordinal value as continuous variable.

6) Number of participants did not equal to 380 because some participants did not provide the relevant information.

7) BMI: body mass index

8) SD: standard deviation

Table 4

Health-related quality of life (HRQoL) scores according to change to a healthy diet after diagnosis of breast cancer (n=204)

1) LS means: least-squares means

2) 95% CI: 95% confidence interval

3) Models were adjusted for age (year; continuous), energy intake (kcal/day; continuous), body mass index at diagnosis (<23, 23-<25, ≥25 kg/m²), marital status (married or cohabitation, unmarried or divorced or widowed), current menopausal status (premenopausal, postmenopausal), education level (middle school or below, high school, and college or above), stage of breast cancer (I, II, III), time from breast cancer surgery (6 month-<1 year, 1 year-<5 years, ≥5 years), and alcohol intake (never, former, current).
