Introduction

Maternal nutritional status during pregnancy plays an important role in the well-being of both the mother and the fetus.¹ Maternal overnutrition during pregnancy, specifically the consumption of high-calorie foods, is considered a public health concern worldwide. It can lead to obesity and adverse metabolic outcomes in the offspring and infant later in life.^{2 3} However, maternal undernutrition is also considered a major contributing factor to adverse pregnancy outcomes.²

During pregnancy, in addition to considerations of the quantity and quality of food intake, it is important to aim for adequate weight gain.⁴ The Institute of Medicine⁴ provides recommendations for adequate weight gain, which are based on prepregnancy body mass index (BMI). For women with normal prepregnancy BMI (18.5–24.9 Kg/m²), the recommendation of total weight gain during pregnancy is 11.33 Kg to 15.87 Kg; in the second and third trimesters the recommendation is 0.45 Kg (0.36–0.45) per week.⁴ In order to achieve these goals, individuals may need to follow a specific dietary or physical activity program.^{5 6}

Food frequency questionnaires (FFQs) are considered useful tools for the assessment of dietary intake. They consist of a list of foods and beverages with various options the participant can check to reveal the frequency in which they consume these items.⁷ The FFQ is widely used in epidemiological studies aiming to categorize individuals into different levels of dietary patterns and to determine their relationships with health outcomes.^{8 9} Many FFQs are validated for Brazilian pregnant women;^{10 11 12 13} however, most of them are considered lengthy, with around 80 to 100 food categories. Issues with long questionnaires include difficulties in handling data,¹⁴ participant fatigue¹⁵ and lower response rates, especially among the elderly.¹⁶

The short-form Food Frequency Questionnaire (SFFFQ) contains 24 questions about regular food consumption, which are divided into main groups that focus on fruit, vegetables, fiber-rich foods, high-fat and high-sugar foods, meat, meat products and fish. This questionnaire was developed based on nutritional guidelines for the United Kingdom adult population and was validated and considered an effective method of assessing diet quality.¹⁷ In order to use the SFFFQ in Brazilian pregnant women, the questionnaire needed to be translated and validated for this population. The main objective of the present study was to translate and to culturally adapt into Brazilian Portuguese the SFFFQ for pregnancy.

Methods

The present study was developed with the authorization of the authors of the original version of the SFFFQ,¹⁷ and followed all the steps recommend by Wild et al (2005)¹⁸ for translation and cultural adaptation. The process of how the present study was conducted to obtain the final version of the SFFFQ in Brazilian Portuguese is summarized in Fig. 1. The original version of the SFFFQ in English was translated to Brazilian Portuguese by two independent researchers, thus creating two different versions (V1 and V2), which were combined into a third version (V3) that was back translated from Brazilian Portuguese to English by two independent translators (Fig. 1).

The present study was developed according to the guidelines laid down in the Declaration of Helsinki, and the cultural adaptation of the SFFFQ for Brazilian pregnant women was approved by the Ethics Committee of the Universidade Estadual de Campinas, Brazil (under CAAE: 62916616.0.1001.5404). Written informed consent was obtained from all participants. Five obstetricians, five dietitians and five pregnant women were interviewed regarding the language content of the SFFFQ, and their opinions were recorded for the cognitive debriefing section of this paper. Then, the final version of the SFFFQ was developed based on the results of the interviews, the discussion with the author of the original SFFFQ validation,¹⁷ and the group's final decision.

Results

The different versions developed as a result of the translation and cultural adaptation of the SFFFQ are presented in Table 1.

1. Preparation

   We obtained the consent of Cristina Cleghorn, MD (University of Otago) (original author of the validation paper of the SFFFQ in English, to perform the SFFFQ translation and cultural adaptation to Brazilian Portuguese, to apply it among pregnant women.

2. First translation

   The first (V1) and second (V2) versions of the questionnaire translations were done by two independent native Brazilian Portuguese speakers (KTK and DSMP). These translations were considered a draft for the next step.

3. Reconciliation

   Versions V1 and V2 were compared to create the third version in Brazilian Portuguese (V3) by another native Brazilian Portuguese speaker (FGS); at this point, details on language were adjusted to create one document.

4. Back translation

   Two back translations into English were done by two official translators, who were English native speakers with experience in medical terms. These translations were done independently based on V3 to compare with the original version of the SFFFQ. After the back translations, some misinterpretations were identified, and these differences were discussed.

5. Revision of back translation

   The author of the original validation paper of the SFFFQ in English (CLC) and KTK compared the original instrument with the two independent versions of the back translation. The two back translations were slightly different (Table 1), and this stage was based on whether the back translations were correctly interpreted from V3. The result of this step was also incorporated into the final version of the SFFFQ in Brazilian Portuguese.

6. Harmonization

   For this step, the comparison of the back translations of the multiple language versions with each other and the original instrument is recommended. However, the original SFFFQ has not been translated to any other language, so this step was not included in the process.

7. Cognitive debriefing

   For this step, 5 dietitians with a mean age of 42.8 ± 10.8 years and work experience of 15.2 ± 10.1 years, 5 obstetricians with a mean age 40 ± 6.2 years and work experience of 15 ± 6.4 years, and 5 pregnant women with a mean age of 29.4 ± 7.8 years were interviewed. These interviews were recorded in an open questionnaire that captured their suggestions regarding the language and the semantic content of the SFFFQ. All the participants were native Brazilian Portuguese speakers and residents of the Southeastern Region of Brazil (in the city of Campinas, São Paulo).

8. Revision of debriefing results

   The dietitians missed the presence of “eggs” as a protein in the questionnaire, since in Brazil it is very common to have eggs as a main source of protein in a meal.¹⁹ Therefore, this food item was included in the questionnaire. The food “corned-beef” is not considered a common food in Brazil, and was excluded from the questionnaire, and “ham” was transferred from the “meat” category and included under the “processed meat” category, since it is more commonly consumed in this preparation in Brazil. In the same way, the second mention of the word “cream” in the “ice cream/cream” category was excluded, since “cream” is not a common item in the Brazilian diet. [“Canned fruit” was excluded from the category “fruit”, as it was considered too sweet, with a high glycemic index, and canned fruit is not a part of Brazil's dietary recommendations for fruit intake. Only “fresh fruit” was considered for this category.^{20 21} All the changes were discussed with the research team, and differences in language were adapted to suit all the regions of Brazil.

9. Syntax and orthographic revision

   The syntax and orthographic revision was developed by a Brazilian Portuguese grammar professor with experience in medical terms. The final version of the SFFFQ was reviewed and approved by all authors.

10. Final report

As recommended by Wild et al (2005),¹⁸ the process of translation and cultural adaptation of the SFFFQ into Brazilian Portuguese has been reported to provide guidance for other researchers considering translating the same questionnaire into a different language.

Discussion

This short communication describes the process of translation and cultural adaptation of the SFFFQ to Brazilian Portuguese, as it is considered the first step toward the validation of the questionnaire for Brazilian pregnant women. Dietary patterns during pregnancy may vary in Brazilian pregnant women,^{22 23} and different factors influence maternal food intake, such as food price policies and nutritional inequalities.^{24 25}

Adequate assessment of the quantity and quality of food intake in pregnant women provides essential information on associations among diet, nutrition and health, the detection of nutrient deficiencies, and the characterization of population vulnerability.²⁶ A study conducted in Brazil showed a different dietary pattern according to the sociodemographic characteristics of pregnant women measured by the FFQ.²³ A restrictive dietary pattern with a low variety of grains, fruits and vegetables was observed in younger Brazilian pregnant women who lived without a partner and attended school or university, while pregnant women with higher maternal age and higher socioeconomic status presented a healthier diet, with more food variety.²³ Therefore, the FFQ has been considered a useful tool to adequately assess maternal dietary habits and to improve the communication between pregnant women and health professionals (dietitians and obstetricians).

During the development of the present study, there were different suggestions made by dietitians, obstetricians and pregnant women about the language content of the SFFFQ. While the dietitians had more comments regarding the food categories and classification, the obstetricians were more concerned with the language content in the questions that were asked. The pregnant women focused on the quantities assessed by the questionnaire and needed clarification on portion sizes. From our perspective, all of them contributed significantly to the development of the final version of the Brazilian SFFFQ.

The present study is similar to various other studies regarding the process of translation and cultural adaptation.^{27 28 29} All the studies followed the recommendation of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) for translating and culturally adapting different questionnaires into Brazilian Portuguese.^{27 28 29} The translated SFFFQ to Brazilian Portuguese can now be validated for use in Brazilian pregnant women.
