Sodium and potassium intake estimated using two methods in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

ABSTRACT CONTEXT AND OBJECTIVE: Sodium and potassium intake from different food sources is an important issue regarding cardiovascular physiology. Epidemiological assessment of the intake of these electrolytes intake is done through food frequency questionnaires or urinary excretion measurements. Our aim was to compare these methods using a sample of Brazilian civil servants. DESIGN AND SETTING: Cross-sectional baseline evaluation from the Brazilian Longitudinal Study of Adult Health. METHODS: Sodium and potassium intake was obtained using two methods: a semi-quantitative questionnaire including 114 food items; and overnight 12-hour urinary excretion measurement. Sodium and potassium estimates obtained through the questionnaire were adjusted for energy intake using the residual method. Urinary excretion measurements were considered valid if they met three adequacy criteria: collection time, volume and total creatinine excretion. Mean nutrients were estimated, and Spearman correlations were calculated. Sodium and potassium intake was categorized into quintiles, and weighted kappa coefficients and percentage agreement were calculated. The significance level for all tests was 0.05. RESULTS: Data from 15,105 participants were analyzed, and significant differences between mean intakes of sodium (questionnaire: 4.5 ± 1.7 g; urine: 4.2 ± 2.1 g) and potassium (questionnaire: 4.7 ± 1.8 g; urine: 2.4 ± 1 g) were found. Weak agreement was found for sodium (K = 0.18) and potassium (K = 0.16). The percentage disagreement between methods ranged from 41.8 to 44.5%, while exact concordance ranged from 22.1% to 23.9%. CONCLUSIONS: The agreement between the food frequency questionnaire and urinary excretion measurements for assessment of sodium and potassium intakes was modest.

Tidak ditemukan adanya hubungan antara asupan natrium, asupan kalium dan rasio asupan Na:K dengan tekanan darah. Kesimpulan penelitian ini ialah tidak ada hubungan antara asupan natrium, asupan kalium dan rasio asupan Na:K dengan tekanan darah.Kata kunci: natrium, kalium, rasio Na:K, tekanan darah, normotensi, hipertensiAbstractHypertension is the blood pressure escalation of systolic ≥140 mmHg or diastolic ≥90 mmHg. This is also called the silent killer because it does not show any symptoms. One of the factors causes hypertension is high sodium and low potassium intakes. The ratio of Na:K that is suggested is 1:1. The objective of this study is to know the differences sodium and potassium intake in patients hypertension and normotension on Minangkabau Ethnic society in Padang. The design of this research was comparative study with the cross sectional approach. The population were taken from Minangkabau ethnic age 35-65 years old in four selected districts in Padang. The total sample of 254 people were taken by multi-stage random sampling. The data were collected by questionnaire of respondents, sphygmomanometer blood pressure, sodium and potassium intakes with a Food Frequency Questionnaire (FFQ). The data was analyzed by Chi-Square test at p-value <0.05 and an average of different test methods Independent sample t-test. The result showed that average systolic of normotensive was 118.87 mmHg and diastolic of normotensive was 76.74 mmHg.

Hypertension is one of the most common diseases suffered by the elderly. At the age of ≥ 40 years, both men and women will be more at risk of hypertension. Many factors play a role in hypertension, one of which is an unbalanced diet. Imbalance intake of micronutrients such as sodium and potassium also plays an important role in the incidence of hypertension. The objective, to determine the relationship of sodium and potassium intake with the occurrence of hypertension in the elderly in the working area of Darul Imarah Community Health Center, Aceh Besar District. Method, this cross-sectional descriptive analytic study used a sample of 60 elderly people (45-55 years) and conducted in the Darul Imarah Health Center in 2017. Sodium and Potassium intake was obtained through a semi-quantitative food frequency Questionnaires. Blood pressure data obtained with a sphygmomanometer. Bivariate data analysis using the Chi-Square test. The results, showed a significant relationship between sodium intake and the incidence of hypertension (p = 0.000), While potassium intake did not show a relationship (p = 1.000). Conclusion, sodium intake can have an impact on the occurrence of hypertension, while potassium does not affect hypertension in the elderly. Suggestion, people with hypertension can reduce consumption foods containing sodium such as preserved food, canned food, use of salt, soy sauce, cheese, and MSG to avoid increasing blood pressure.Hipertensi merupakan salah satu penyakit yang paling banyak diderita oleh lansia. Pada usia ≥ 40 tahun baik pada laki-laki ataupun wanita akan lebih beresiko untuk menderita hipertensi. Banyak faktor yang berperan dalam penyakit hipertensi salah satunya adalah pola makan yang tidak seimbang. Ketidakseimbangan dalam pengaturan zat gizi mikro seperti natrium dan kalium merupakan salah satu faktor yang berperan penting dalam kejadian hipertensi. Tujuan untuk mengetahui hubungan asupan natrium dan kalium dengan terjadinya hipertensi pada usia lanjut di wilayah kerja puskesmas Darul Imarah Kabupaten Aceh Besar. Penelitian deskriptif analitik berdesain srossectional ini menggunakan sampel sebanyak 60 orang usia lanjut (45-55 tahun), dilakukan di Darul Imarah tahun 2017. Asupan Natrium dan Kalium diperoleh melalui food frequency Questionaire semi Quantitatif. Data tekanan darah didapatkan dengan spygnomanomater. Analisis data bivariat menggunakan uji Chi Square. Hasil penelitian menunjukan hubungan signifikan antara asupan natrium dengan kejadian hipertensi (p= 0,000), sedangkan asupan kalium tidak menunjukan hubungannya (p= 1,000). Kesimpulan, asupan natrium dapat berdampak terhadap terjadinya hipertensi, sedangkan kalium tidak berdampak terhadap hipertensi pada usia lanjut. Saran, penderita hipertensi dapat mengurangi konsumsi makanan yang mengandung natrium seperti makanan yang diawetkan, makanan kaleng, penggunaan garam, kecap, keju dan MSG untuk menghindari peningkatan tekanan darah.

ABSTRACT CONTEXT AND OBJECTIVE: The food frequency questionnaire (FFQ) is the preferred instrument for obtaining dietary information in epidemiological studies. A short form of the FFQ was compared with the original version that was used in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), and also with three 24-hour dietary recalls. DESIGN AND SETTING: Cross-sectional study carried out in six Brazilian state capitals. METHODS: Multiple linear regression was used to reduce the original food and drink list of the FFQ, which had contained 114 food items. The frequency of consumption and nutritional composition of the foods were also taken into consideration. To assess the validity of the shortened FFQ, the energy and nutrients values of the 24-hour dietary recalls were deattenuated and log-transformed. RESULTS: The list of the FFQ of ELSA-Brasil was reduced to 76 food items. The intraclass correlation coefficients in the validation study ranged from 0.17 (selenium) to 0.66 (calcium). CONCLUSIONS: The number of items was reduced by 33%, while still maintaining relatively good capacity to measure energy and selected nutrients.
